As far as is known this Mustang was not assigned to the 361stFG. It was assigned to the 8thAF (according to Curtis Fowls Mustangs site information) but unknown if to a group before return to the US.
The squadron code 'A7' was not a 361stFG squadron code (B7-374th/E2-375th/E9-376th).
As far as the name 'Never Miss' in the bomb symbol, it was a variation of Urban Drews 'Detroit Miss'. No other known P-51 in the 361st used the bomb symbol except Drews Detroit Miss.
As a 361st descendant I would love to see it wearing correct squadron markings at the minimum. That would not be a big change to do.
