Just grabbed my first coleman lamp got it up and running within a few hours just thought I'd share...
@Litemygas Welcome to CPL. Apologies for my abrupt question — I got called away just as I started typing. If I’m correct, the 117 “slant” lamp has the filler cap/check valve with the fitting for the external pump; the 118 slant lamp has the integrated pump. Edit: It could be that the pump can’t be seen in the photos, and that the filler cap is not original. It would be good to see any stamping (on the bottom of the tank). Nice lamp! Cheers Tony
