Stove Pump, Very Early, Used - E1133

SKU: 415C520 Very Early Used

Used pump for very early stove models 2G, 9G, 2H, 9H, 4F, and 6F. Leather has not been replaced but seems to be in decent shape. These are longer than a lantern pump and measure 5 3/8" long.

The official diagrams for these stoves show it taking the air stem and standard check valve. These pumps have been documented fitting into the models above in real life, but the diagrams do not call them out and shows them using standard air stem/check valve. These pumps work only on a check valve that does not accept a traditional air stem and have a non return valve that takes a pip. Mystery for sure.

Each has two holes in the cap insert - holes are threaded on two and one has no threads. May be the first pumps to use clips to hold the pump in but used the 242 type cap at first then moved to the caps without threads. Threads are hard to use on a stove tank where the pump enters the small end as installing a screw is about impossible.
