WWII Spitfire Wobble Pump
Here we have a very nice wobble pump. Probably one of the better ones that I have come across online.
Wobble pumps were fitted to early Spitfires that used Bendix-Stromberg carburetors where no electric booster pump was fitted. The purpose of this hand pump was to ensure a good fuel flow when switching between the main fuel tank and the auxiliary slipper drop tank and back again.
Later when electric fuel pumps were installed the wobble pump was retained as a back up and to save the batteries during engine start up. Eventually wobble pumps were phased out in later Marks of Spitfires. This pump would be found on the starboard wall of the cockpit as shown and was attached using a specialized mounting bracket which is available too in a separate listing.
