Yes, please - if you wouldn't mind I'd like a photo of a main wheel.
If I understand correctly, the mains didn't change throughout the 38's different versions - only the appearance changed due to leaving the wheelcovers off. First noticed that on the H. Sometimes I've seen photos with the nose wheel uncovered and the mains covered.
From your nose wheel shots, seems clear that its 4 fasteners in a square pattern.
Thought I saw a early war skin - P-40B or E maybe, with a triangular pattern of 3, and then start second guessing myself after looking at the Aleutian 38E photo I posted.
Thanks help, Bodhi.
