Merkel clone thru and thru and built at the the same factory in Suhl. Choked full/mod which is standard for those guns. Without ejectors it would be a Merkel model 8, with ejectors you've got a Merkel model 47E. Should be marked on the barrel flats when its made and based on your paperwork those markings would be 876. Should also be marked on the barrel "made in GDR" I'm guessing as thats before reunification. That's the way we all want them. Saw lots of them when I was stationed in germany. Great pics btw.
