I've found what I believe might be a slight inconsistency with the real world aircraft in the model, in addition to the one already discussed about the wing thickness.

The transition from the dorsal fin to the tail seems to be too "soft", and more aligned with how the newer TBM models look.
The TBM 850 however seems to have a sharper angle between the two. Has there been any modifications on this part of the tail over the years?

I'll add the same picture as I did in the other thread, as they show this quite well.
