1947 Drone “B”ee .29 Diesel

Lovely engine with after-market, factory variable compression head. It also has its original fuel tank, with gits cap, the original box, a Drone prop and a copy of the instructions. Serial# 798

Engine Description

Interestingly, the fuel mixture recommended for the Drone does not include any kerosene/diesel, just ether and oil!  This might explain how the engine was able to run with a fixed compression head and why the variable compression head was a popular upgrade, allowing the use of other fuel mixes.
