they were made in Elisabeth NJ in the late 1940s and early 50s by Leon Shulman I went there and bought mine at the factory as a teenager martin
fuel 30% mineral oil and 70% ether from the drug store
the fuel mixes now are conventional of course with lower ether % kerosene and castor oil that was the original formula suggested by drone back then
Quite sure they would do fine on our newer blends
my drone is shot poor compression so a no run
