UBB.threads Forums Edged Weapons SA & NSKK Dagger Forum NSKK chain RZM marks

i was looking at a NSKK Leaders Dagger . It's a double marked Hollar dagger and the chain is marked with the RZM code M5/25 but is marked on the clip not on the chain. I have only seen the mark on the chain and wonder if this is the mark of a fake chain?

Need pics to be of help.

Thank You for your response. I passed on the dagger as a well-known dealer told me it was a great dagger but a bad chain. You're the only response I got in 2 days.
