John,
The grip gauge is not dual sided to me. I guess that the second one is simply missing. The gauges set contains 97 pieces but is not complete.
Hard to say how many gauges were made. You are right, the grips of the 06/73 model have a hole for a pin that goes trough the frame and fix them properly.
Steinar,
Most of the gauges have the Mauser Banner and some of them also the JW mark. All of them have a serial number.
We try to investigate the meaning of the composed serial number. The first part, what I call the "family" indicates most probably the gun for wich they were made. I have two set in my collection, one for the Parabellum and the other one most probably for the carbine model 66.
Then there is another number that indicates for which particular item the gauges are for. For example, all the gauges applicable to the breech block have the same number and so on...
In the picture you can see: 2313 means Parabellum, 2500 breech block and we still don't know the other numbers...
I guess that at least two sets have been produced because I have a couple of double gauges.
We are still investigating the matter and we do not exclude finding more interesting information. If yes, I will share them with the forum.
Have fun,
Mauro
