Could you pleasure us with an better image of the 1st pic?

Looks like a Sauer Quality Crown and look on the extractor face to see if a >>70<< is stamped there.

I would steer away from >>light target<< loads and look purely at the pressure values for each cartridge.

As you said, for export & most of the time the importer / retailer didn't want to pay the extra pfenning for the Voluntary semi smokeless proof.

Is it listed in G&H's list or was it a Daly import?

Cheers,

Raimey
