Got this one today. I bought this at an auction, the seller knew nothing about it and the other WWII items in the lot were authentic IMO but I know nothing of these buttons. After researching the forum I found that the TK buttons with the same M5/8 rzm mark had some controversy behind them; some think they are period and others don’t like the M 5/8 buttons. Anyhow, here is mine and I would appreciate some opinions on this one.

Thank you in advance.
