Ben. I bought one of the VZ-24's offered by Cleavers over 12 months ago. It was a well done refurb.. On the left side of the reciever ring is stamped Waff. Sch..

I believe the mark identifies the German firm Waffen Schumacher GmbH, a present-day firearms dealer and exporter. Their site is: http://waffenschumacher.com/

It would be interesting if the Chilean 7x57 came through the same firm.
