Built of mahogany veneers impregnated with vinyl and phenol in an attempt of construction without the use of strategic materials, the first model was the 2-4-65 and flew in 1940. The second model was the 2-4-90 which flew in 1941 and was taken on by the USN as the XNL 1. However, when the U.S.A. entered the war the phenol and vinyl used in the manufacturing process were found to be in short supply and so no long term manufacture was made.

I flew one for about 1 hour in 1950; It was a plywood duramold airplane. Easy to fly but noisy. It really carried four souls.

I flew one of these in 1955 at Sunset Beach Airport, Orange County, CA.
My understanding was that it was built as a basic twin engine trainer for the Navy. It had an unusual bungee setup for single engine to help with the rudders.

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?
