I just got the lanterns that I bid on from Ebay over the weekend and they are great I'll post pictures as soon as I have a chance.
My question is I thought I read somewhere that all Coleman laterns have a date stamped in the bottom of the tank. 2 of the lanterns that I just got are a 242B and a 220 [not sure of letter its not stamped well]
They are both nickle tanks but I can't find any dates. How do ya find out how old they are.

They are all in petty good shape they just need gone over and fixed up a little. New seals on the pump and then see how they burn. The 242 needs a new glode the one that come with it has a crack in it.
Have a great day.
