VERY RARE, unused example of an Anlasskraftstoff (Fuel Priming Pump), 8-4506 B-3, as used on the Me109 and Fw190 fighter aircraft! This pump was located on the left side of the cockpit, right next to the pilot. It allowed the pilot to manually prime the engines before start-up. Used for all models of the DB605, BMW801, and Jumo213 engines. There are no breaks or damage, and it is 100% functional. NEW, TOP CONDITION.
