I'll keep looking uptown, but since I joined the 39th I was looking for a J or L to paint for the squad, as at the time there were both J and L's available, now only L's (if you have a suggestion... hint.. hehe) , but I believe by the time the J came out (43?), the 39th was flying either their currently assigned 38Fs, Gs, or Hs, or being moved toward the Jug and later Pony.
If you can prove me wrong though, I'd be happy to hear it =)
