I spoke in length with Doug Smith of FGS on the phone this week about this # 3721v. Doug cautioned me that most of the "short frame" 06/34 Swiss Mauser he has seen were not authentic.
He was particularly interested in knowing if mine had an original reinforced frame or not.
I will make plans to bring this # 3721V to the SE NAPCA event in TN this coming up August...where Doug will have an extensive display of v-series lugers...it will give Doug a chance to do a detailed inspection of my luger as well.
As a side note, Doug indicated the odd "F27+" stamping on the underside of my thumb safety is an arsenal replacement.
The spring of my grip safety (as you can see in the photos below) looks to also be a replacement of some sort...
In the mean time, I am posting photos of the frame on my piece...would appreciate other Member's opinions about my frame's reinforcing :
(LF member Doc Fisher has also asked to see photos down into the rear frame well. I will do so in 2 weeks when my camera is back from the repair shop.)
