That's what I figured, AgX. Freestyle seems to have a bit of remaining Efke stock at present, but other than that, only Rollei Crossbird and Nightbird are available. It seems that with regard to "regular" B&W and color negative film, the 127 format is pretty much dead now.
For a wartime 35mm I second the Kodak 35, from what I recall Kodak made a miltary version is olive drap or black, I have seen a few that were modified for use with parascopes. But the Speed was the most common camera in use, at the end of the war the Combat Speed was issued and were used as late as Vietman.
