Hello guys,
I just verified my Bulgarian commemorative (first commemorative made - 1975) and my LP08 commemorative (last commemorative produced - 1986). Both pistols have engraved on the rear toggle part the last digits of the serial number. The Bulgarian the last three digits, the LP08 the last two.
It means that this habit was implemented in Mauser during all the production period.
For any reasons during the production the frame was dissociated to the toggle.
For this reason was necessary to "remember" which toggle belongs to which pistol.
Now why it was necessary? I assume all Mauser Parabellum items interchangeable therefore why...
Merry Christmas
Mauro
