Douglas O-31 or O-43?

Can anyone help with cockpit or gunner's position photos of the Douglas Y1O-31A/B/C (O-31) or Y1O-43 (O-43)? Any help much appreciated.

May I suggest Mr. Peter Westburg's drawings? I believe he did a set of the Douglas parasol plane.

I think I have these: no schematics of the crew stations however.
