Richard firstly sorry about Your man in work, i hope all would be better, with them.
To Your scans, certainly some of them are confirmed,i mean the DH, but as mentioned earlier they are from rework rifles, that were done only for short period, majority should be proofed with commerzial Nitro proof, and it doesnt mean that the stamp used prewar should be continued to end of war on items, that were not destined for.The DH in lower part of 9552 looks like engraved, and i have my doubts about it. It looks like on rifle slot of bayonet? Anyway there are certainly proper stamped DH but for what for purpose there are stamped i dont know still. Is only opinions as exist no documents about this type of stamps. Unfortunally the small pictures without link to real items could hard explain the overall proofing system. Timeline is very importing thing, as 1933-39 were one period of SS and 1940-45 other period.best regards,Andy
