Herb and Dave,
Thank you for the reply.
I think this absolutely interesting. Actually the pistols with more engraved parts belong to the Bignami contract for Italy. The Mauser Italian Importer asked for a special contract in the 1986-90 era with LP08 and P08 in 7,65 mm. The quality of these pistols is greater than the normal production. This can justify that the parts were checked and numbered with more care than the normal production.
I will continue to investigate this area.
Thanks
Mauro
