OK, I checked in-game and the existing 61st FS P-47 skins are:
HV-K "Sue" by Fencer
HV-Z (Polish flag) by Kazan
HV-M "Pengie" by Kazan
The only other one I've found so far is HV-W "Lil Snorkey". The only problem with this one is I can not make out the tail airframe number which was generally painted in red on the black and so does not stand out well in B&W.
There's an AH BBS post on P-47M skin ideas with a photo of this plane
here and some history in this Van's Air Force BBS post
here.
Edit: Just found photos of HV-Q "Joy Boy" and HV-J "Lorene". HV-J currently looks favourite as it has the best nose art.
