I have a few Coleman lanterns as well, “Sunshine of the Night”!
Not as many as you but, I have a LOT of weird other Coleman pieces, picnic table (with stools) stupid amounts of coolers, a few stoves, one heater(old style) sundry other small items.
I think its almost as bad as Weberitis, I had to stop, I was looking for laMPs and decided I was spending too much. Caught that one in time. Gave away a few to family members.
To be honest, right now the few I have left are buried in a back corner of the garage in a locker! Spring will see a large purge of stuff! I’ll keep the two or three Coleman lanterns as well as the oilers. Much will be knackered or given away. I can’t keep all of this stuff!
