Thanks for your feedback, GFR. I don't really know. The lower part of the engine cowl was modified several times, as more pictures came in.
The actual shape is mostly based on the picture sent by Joe and also on a good side shot of the nose that can be found in Squadron/Signal's Walk Around of Allison Mustangs.
This is how the nose looked initially:
IMO, it looked a bit too "chunky" and had something of a Spitfire look.
Based on several photos, but especially the ones mentioned above, here is the corrected version:
Looking at that photo of 41-37321 that you posted, it seems to me that the corrected version is right.
Or am I missing something?![]()
