Ah, you mean those Mustang tank-busters in 78th FG colours, portrayed around June 8th, 1944 - when the 78th still had P-47s ......
Going back to the original topic - I can understand having an airworthy MkIX painted in, for example, a BoB scheme or one similar to replica depicted, perhaps as a dedication, or anniversary, or for movie or TV work. But a glass-fibre replica? If going to the trouble and expense of obtaining a replica, then why not have it in a scheme to suit the Mark, or the opposite, a Mark to suit a chosen scheme?
Ah well, it's 'their'' replica I suppose.
