Dear Tiger205
of course I’ll give you following important hints:
- the role of the mystery aircraft was observation
- nationality: USA
- first flown in 1938
- only one built
- engine was a Pratt&Whitney 1340-36
- it had a double denomination as it often happens with US aircrafts
I’m pretty sure this is going t o secure name of this a/c
Cheers
