This Optimus Model 100 lantern
was made by Aktiebolaget Optimus in Sweden.
It is in Bo Ryman's collection.
This kerosene model is 100 cp
and holds 0.75 pint of fuel.

Similar to the Model 100 above, this 100N
was made in the 1950's, near the end of pressure lamp manufacturing in Sweden,
according to Bo Ryman.
This lamp, in Darcy VanTiger's collection,
has a modified handle and
a bracket was added by a previous owner, perhaps for wall mounting.

After an initial design of Model 200 that was only made in 1930,

Optimus modified the design as you see above,

which was produced from 1931 to about 1935.

This version, in Frederik Tivemark's collection,

can be identified by the filler cap and generator type.

The ventilator cap is held in place by bracket on this early version.

A mica globe was optional in this period; this one is a reproduction.

The Model 200P Optimus on the left was owned by the Swedish Civil Defense, as signified by the yellow stamp.
Many were sold to the public in 2000 when the Army reduced its inventory at surplus stores.
This military version of the model lacks a pressure gauge and air bleed screw.
The version on the right, Model 200G (but marked 200P on the fount) in Frederik Tivemark's collection,
was made circa 1973 based on printed material in the box and includes a manometer.
This kerosene model is 200/300 cp and holds 1.25 pts of fuel.

Optimus Model 1200 is similar to Model 200 above
but includes a rapid preheater that is controlled by a valve wheel.
Frederik Tivemark, whose collection this is in,
dates this version to the late 1940's - early 1950's.
The pump and pressure gauge are on the opposite side of the fount
and not visible in this image.

The only markings on this lantern are Petro Delux, Made in Germany, 350CP.
The lantern is preheated with alcohol and is kerosene fueled.
Erik Leger found that the parts of this lantern, which is in his collection,
are similar to a comparable model Petromax,
as well as to lanterns made by Petro-Pintsch (below) of Germany,
and Providus, of Italy.

This 300 cp kerosene lantern in the petromax style
is stamped Petro-Pintsch (Julius Pintsch AktienGesellschaft), Germany
on the fount and similarly etched on the globe.
This unfired lantern is in Christian Leopoldt's collection.

The Powerlight Co., Winnipeg, Canada, made this Match-O-Lite brand lantern circa 1920.
The fount and, I believe, valve stem assembly
were made for Powerlight by Nagel-Chase Mfg., Chicago.
The burner was patented by Powerlight.
The once chrome plated steel frame base plate/collar and ventilator have been painted.
The globe is a reproduction from Fred Kuntz.

The Indo International Division of Prabhat Udyog Limited, Mumbai, India
manufactures several "petromax style" lantern models under the Prabhat Brand.
This Model 425, in Doron Papo's collection, is a 300 cp kerosene model.
This lantern has a red plastic sleeve on the bail,
a feature that is found on some of the other models from India.

The Radius brand was manufactured by Aktiebolaget Radius, Stockholm, Sweden.
Radius Model 102 (left), seen running in this image, is a 200cp kerosene model
that is preheated with alcohol.
Model 103 (right), in Frederik Tivemark's collection, is a 300cp kerosene model.
The alcohol cups includes a visible stem to direct part of the flame to the mantle for lighting the kerosene.
The windows to the left in the fount shows the fuel level;
it utilizes a cork on the end of a pivoting wire.

The Radius 108 lantern (left) is a little taller than the similar Optimus 930 model (right).
Neil McRae dates his 108 lantern to the 1950's or 60's.
Both are 300 cp kerosene models.
The Optimus is fitted with an optional glass handle,
which, with a shade, would be used in the home as a lamp.

Radius Model 115, in Dan MacPherson's collection,
includes a preheater torch and came in 300 and 500cp versions.
and is correspondingly built with a higher collar than the Model 119 below.
The pump has a bail to hold the pump handle down.
This model appears in a 1939 catalog and another of this model
came in a box with a 1942 date stamp.

This Radius Model 116 is also stamped Statsbanene = Norwegian State Railways.

The lantern, in Harald Hogseth's collection,

has a REVOLTO torch preheater mounted on the filler cap (right)

as well as an alcohol cup for preheating.

The tip cleaning lever (right) is marked Öppen (open) and Stängd (closed).

This model is kerosene fueled and is rated at 300 cp.

Radius 119 is a 300 cp kerosene model
that was made in Sweden by Aktiebolaget Radius Stockholm.
Neil McRae, who owns the lantern on the left, speculates that all the Swedish companies
must have licensed the burner parts from the German consortium
of Hugo Schneider, Hirschorn, Erich and Graetz, and Standard Licht
as these four companies jointly patented the helical coil generator around 1927.
The military version on the right has a cook top surface.

The Rinnai Corp. in Japan made this lantern in the mid 1960's
as Western Field brand, Model EKW 9516A for Montgomery Wards (left)
and as Model 60-9516 with a green fount and red porcelain ventilator.
The pump handle has two parts at the end
that must be separated to lock it down,
as explained on a decal on the back of the fount.
The lantern on the right is in Thomas Kivler's collection.

Phoebus lantern models, # 611, left, and #615, right,
were manufactured by Metalwarenfabrik Josef Rosenthal in Vienna, Austria.
These lantern models have gold painted steel founts,
green enameled ventilators, and their original metal carrying cases.
Henry Plews owns the #611, which is a 200 cp? gasoline model;
Neil McRae owns the # 615, a gasoline/kerosene model.

Phoebus Model 621 is a gasoline fueled, 200 cp lantern (Neil McRae).
The red valve wheel (left) is only for the tip cleaner,
while the black valve wheel (right, opposite side)
is for instant lighting and running the lantern.

Phoebus Model 631 has a bail that has been modified with a long loop
that engages a post on the ventilator so that it can hang at an angle.
This feature minimizes the blockage of light on a subject.
This lantern is in Henry Plews's collection.

Phoebus Model 635, in Doron Papo's collection,
is a 300cp kerosene fueled lantern model.
Neil McRae notes this one is unusual
in having a Bakelite knob
and brass finish.

Neil also owns this Model 665 Phoebus lantern,
a 500 cp kerosene model,
which is seen in operation in this image.
To replace the gasket on the filler cap
he had to unsolder the filler cap from the pump tube
and resolder it after replacing the gasket!

This lantern is identified on the fount bottom: Louis Runge - Berlin.
Anton Kaim directed me to German Patent 400248
that was issued on December 15, 1923 for this model.
The lantern is made of nearly all brass parts and includes a tip cleaner;
the original generator is gone but has been replaced with a Coleman R55.
The mica globe (not seen here) was a likely replacement (Coleman) as well.

This Santrax lantern, Model 829,
was made by Santromax Ltd., Hong Kong,
and is chrome-on-steel construction.
It is another 500 cp version in the Petromax genre.
This one is in new condition
and is in Brien Page's collection.

These Model 551LD lanterns were made by Eugene Schatz Zuger Lampen, Zug, Switzerland.
This post WWII model appears to be a variation of the Hasag model 551,
the variation being the alcohol cup seen to the left of the globe base (left image).
The lantern on the left is in Herman Mulder's collection,
while the lantern on the right, shown hanging for hospital use by chains
and with a lens to focus the light, is in Henry Plews's collection.

This lantern was probably manufactured before 1928
by Hugo Schneider Aktiengesellschaft, HASAG brand, for
Provincial Incandescent Fittings Co., PIFCO brand, in Manchester, England.
It is their 400 cp gasoline, single mantle Model 1405.
Neil McRae polished this lantern to brass
since the nickel plating was almost gone.

Hugo Schneider Aktiengesellschaft or MEWA (see below)
made this Kerolux Model 103 lantern
for an importer in Buenos Aires, Argentina.
This lantern, in Juan Caiti's collection,
appears to be a 500 cp model.

The Hasag Model 34 is a 100 cp kerosene lantern.
From its good condition, Neil McRae,
whose collection this is in, assumes it is post WWII.
If so it was made by MEWA in East Germany.
The tip cleaner needle in this one is broken
which prevents its operation.

The Hasag Model 42 lantern on the left, in Henry Plews's collection,
and Bat Model 42 on the right, in Neil McRae's collection,
were made by Hugo Schneider Aktiengesellschaft and MEWA respectively.
Neil notes the puzzle here that the Bat is post 1949 and the Hasag is identical
but the Hasag brand was supposed to have died in 1945.
Neil suspects that MEWA, an East German company,
used the Hasag brand as well as the MEWA brand during the 50's.

MEWA (Metall Waren Kombinat), Leipzig, Germany
made this Model 351L lantern after WWII.
This lantern, in Tobias Jesse's collection,
has a glass globe with a hole to light the preheater.
Tobias's restoration included repainting to match the original color.

Neil McRae took the picture
of this unknown lantern in Henry Plew's collection.
It is marked "882 Made in Germany"
on a brass plate riveted to the support collar.
Petromax made a Model 882 table lamp.
Hasag made other lanterns with blue enamel
so it may be a post WWII lantern made by MEWA.
Please contact Henry Plews if you have further information.

Neil McRae found this lantern in England.
It bears some resemblance to German made
BAT and Hasag lanterns he has in his collection.
The logo in the base (right image) is a complete mystery.
Please contact Neil McRae if you can help him identify it.

This 200 cp Model 5022 Standard lantern
was manufactured by Standard-Licht-Gesellschaft m.b. H.,
Frankfurt am Main, Germany.
Neil McRae modified the burner with a 250 cp gas tip
and opened the air gap a little to get it running as seen here.

Standard-Licht possibly made this Model 2045F lantern in the 1930's.
It is 200-300cp but the reflector makes it 2000 reflected cp.
The steel fount lantern is unusual in being able to use gasoline
as it has a positive needle valve shut-off
and the check valve is on the shoulder of the fount (left in the images).
The lantern has a rapid preheater just below a bend in the generator.
This lantern, in Neil McRae's collection, is similar in design to Petromax Model 850.

Two more Standard Models, 5122H (left) and 6112H (right).
Neil McRae was able to run the 5122H by using a 250cp Petromax generator
Neil got the 350cp 6112H lantern from Thailand.
The label seen on the base rest appears to have
the importer's name in three languages:
Chinese, Hindi, & Thai.

Standard-Licht-Gesellschaft m.b. H.
also made this floodlight which Neil McRae, whose collection this is in,
believes to be Model 3517M.
This is a gasoline fueled model based on the lock down needle valve on the pump.
The fount holds 2 liters of fuel.
