The manufacturer of this lantern is identified
as American Gas Machine Co.,
a Division of Queen Stove, Inc. Albert Lea, Minnesota.
It is Model LRL21B.
The pump is more cheaply made of aluminum
and there is no screen in the burner cap
so that the fuel air mix can ignite in the burner tube making a popping sound.

American Gas Machine Model 2471 probably predates
Model LRL21B above as the company name doesn't include Queen Stove Works.
It has the same generator and burner type as the above
but the generator is threaded to the burner
and the air tube connection to the burner is a casting, not stamped.
The brass fount had stress cracks that I sealed with an automotive gas tank sealer (left)
the maroon version of this model (right) is in Joe Pagan's collection.

The AGM Co. became the Queen Products Division
of the King-Seeley Corp. and remained in Albert Lea, MN.
These KampLites, Model LRL22 (left), RL33 (center), & LRL42 (right)
were possibly manufactured in the '60's.
Models LRL22 and LRL42 are single mantle lanterns.
The lanterns in the center & on the right are in David Jahn's collection.

This pair of lanterns were probably made by the Queen Products Division as the preceding,
but have decals identifying them as J.C.Higgins lantern for Sears Roebuck & Co.
Model 710.74001 (left) and Model 710.74011 (right) are both single mantle lanterns.
Apparently earlier versions of these two models, 710.74000 and 710.74010,
have Coleman style pump handles and larger decals.
The unfired 710.74001 on the left is in Zack MacGregor's collection.

AGM made this Hawthorne Model 60-9520 (left)
two mantle lantern for Montgomery Ward.
It differs primarily from AGM Kamplite Model RL-32B (right)
in having an aluminum (not steel) filler cap
and having the bail attach to the globe cage
rather than being inserted into holes in the burner casting through the ventilator.

The KL-2 KookLite doubles as a lantern and a stove.
With the shield open (left image) the lantern casts a directed light
and, with the top vent plate open and the feet extended,
it serves as a stove/warmer.
This lantern is in Brien Page's collection.

The most unusual lantern produced by King-Seeley Corp. is this
Thermos 8321 doughnut or inverted model (left) and as KampLite (here Model IL-11B) in red.
The lantern on the left is in Neil McRae's collection,
while the lantern on the right is owned by Bruce Bandow/Lila Richards.
The IL-11B has the original 7506 mantle; this lantern has never been lit.
Since the fount is above the light they cast no shadow when used as a hanging lantern.

Two views of the KampLite Model IL1 inverted lantern,
the first lantern by King-Seeley Corp. in this series.
This model had two spherical nuts, not screws, holding the ventilator on the top
and the older and presumably more expensive pump assembly.
This lantern has the optional reflector fitted in the right image.
This lantern is in Brien Page's collection.

Another color version of the KampLite IL-11B model,
comparable to the LRL22, RL33, & LRL42 models above.
This lantern is in David Jahn's collection.

This mil-spec lantern is stamped 1963, U.S., Macomb Plant,
Thermos Division, King-Seeley Thermos Co., Macomb, Illinois.
This is the only year that Thermos had a contract
to build this model for the government.
This lantern is in Andy Sorensen's collection.

Thermos Model 8311 is a single mantle lantern
that lacks the ventilator "dimples"
and indentation in the collar to reach the match lighting hole
as seen in Model 8312 below.
This lantern is in Thom Kivler's collection
and has the original Davisil British made globe.

This single burner Model 8312 Thermos lantern (left)
was re-badged as Blue Grass Model D98-BG8312
by Belknap Hardware & Mfg. Co, Louisville, Kentucky.
The same lantern as Ward's WesternField 60-9522 (right)
which is in Thom Kivler's collection.
The single mantle models are about 3/4ths the size of the 8325 and 8326 models that follow.

Thermos Model 8325 (left) may have been a short-lived predecessor
to Model 8326 below.
On the right it is badged Hawthorne 60-9536 for Montgomery Ward
This model differs from Model 8326 in lacking dimples in the ventilator,
separate fuel filler and pump,
and in indent in the collar for the lighting hole.
The lantern on the left is in Thom Kivler's collection,
while the lantern on the right is in Don Colston's collection.

A very common lantern is this Model 8326 double burner Thermos.
The original box that came with the Holiday Thermos
(right image) is dated Feb. '63
Note the indented globe rest to provide a lighting hole
for the mantles, a feature that is present on both the 8312 and 8326 models.
The lantern on the left is in Chris Fearon's collection.

A different badge on the Thermos 8326,
this lantern was made by Thermos for the US Coast to Coast store chain.
The collar identifies it as Model 8326,
but the box it came in identifies it as Model 8326M29.
Usually this model was given a different number when it was rebadged.
This lantern is in Thom Kivler's collection.
