Anyone care to hazzard a guess on this early contra-rotating effort from the USA?

Looks like it's incredibly dangerous to start.....

Tracked down this oddball. From a 1933 issue of Flying Magazine-




Aerofiles entry:

Brown

C L Brown, Rushville MO.1931 = A kit-built Heath with its original 25hp Heath B-4 replaced by a two-cylinder Cleone modified by Brown into a rotary engine, and with the housing attached to another propeller, of opposite pitch, at the rear. This two-prop arrangement theoretically would do away with torque and add more thrust, but in real life it created more problems than it solved, and the machine never got past a fast taxi. (It did fly!)
