In doing a little more research on this pistol, it looks like the example written about in Mr. Kenyons, Lugers at Random, pages 258 & 259. In that case this luger is even more valuable. IMHO.
But Ken and Doug at FGS, advertise it as a Swiss 06/34 with probable good reason......... If Ken or Doug told me it was gonna rain for 40 days and 40 nights.... I'd go looking for a raincoat.......
