Aircraft was FAA/CAA Type Certified Model 4-2-90, a twin using Franklin 90 hp. engines with fixed pitch propellers. Five were known to be built. Manufactured of special heat formed aircraft plywood "Duramold". Fixed landing gear, four passenger. Could fly around 120 mph. In the 1960's one located in Tulsa,OK.

I strongly suspect that the skin of that aircraft is plywood. That would explain the "grain" we see, and it was a common material from which to craft an aircraft in that time frame.

It looks as if it is of composite construction. Would that have been an option at that time?

Do you have any comments about this aircraft ?
