Hello all,
As described in the article, Mauser started writing the sight graduation from 1927 on.
Alvin, you found the good example in the great Jon Speed book and maybe you like see the original...
What it is interesting analysing the inventory and sales records is the amount of "special" configuration Mauser was doing following the request of dealers and clients.
You can notice in this list is 33 Engraved examples and one Super interesting example that says with Extra MAGAZINE !!
