1940 Hand Operated Fuel Pump

Today’s object is a little bit of a mystery as am still not entirely sure as to its precise use. It is a small hand cranked pump, rather larger than a standard ARP stirrup pump:

This pump is entirely made of iron, so this would tend to suggest it was not for use with water and the best guesses I can come up with was that it was for use with fuel, for instance to top up the fuel tank on a towed fire engine pump. The pump has a cast central panel which has the date, 1940, and the Royal Cypher cast into it:

This suggests to me that rather than being military in origin, this pump is civilian but for a Home Office department such as the Auxilliary Fire Service or the ARP. The pump itself has a small handle that rotates back and forth to move the fuel up from one receptical and force it back out into another:

A narrow inlet is positioned on the opposite side of the pump which would have originally had a narrow rubber tube attached:

A large metal canister is attached to the top. This acts not only as a handle to rest your hand on to steady the pump when you are using it, but, as it is hollow it may be used to act as a pressure accumulator keeping the flow of the liquid steady once it’s been primed:

A large cast foot is provided to rest the pump on, presumably the full can of liquid is rested on this to help hold the pump steady.

A lot of this is speculation as I have struggled to get a positive ID or any photographs of the pump in use. If you do know anything else about this pump, please comment below.
