The double mantle lantern is an AGM 2572, its in fairly rough shape, most of the paint on the base is compromised and the top has some significant chips out of it. The pressure pump and gas cap seem to both work correctly (a first, usually the pump's leather is dry) but the packing around the valve leaks. I'm going to try gently tightening it but it'll probably need replacement. Assuming its the same size as the Coleman 220F I've got it's easily obtainable.
I haven't found out much about this lantern, it seems uncommon, at least when compared to the 3016 which I've seen several of. AGM (then owned by King-Seeley-Thermos) seems to have stopped producing lamps in 1968 so mine must be older than that.
I tried to order a pump for the Kerosafe today but Lehmans' says they're out of stock. I tried to contact them to ask when they'll be in stock but their webpage won't accept any email address so I don't know if my messages are getting through. At any rate that same page, which used to be excellent seems to have gotten mostly broken in a redesign. In the meantime I'm trying some other sources.
