ob,
Mauser made around 12600 plus actions, but not all were made into Mauser factory rifles, as many actions, and sometimes barreled actions ?? were supplied to the trade, eg John Rigby &Co

The lastest I have ever owned was an "S" Type numbered 126500ish if memory serves my right. I can tell you that the quality of that particular rifle was fantastic by todays standards, but not n the same street as the 30-06 that RHB has.
I will try and post a pic of a Kurtz Type A that I once owned.
