It does have a high gloss or varnish on it, the german eagle on the butt plate, looks like it could have a nazi symbol at the bottom of it. The butt pad is possibly an add on to make the gun longer and add protection from recoil??? but the original butt plate is on the back of it. The pad may be original I don't know. Thanks for clarifying the caliber of 9 x 47. I have never seen one in that caliber. I would like to know the approximate worth of it, if anyone knows much about it, Thanks guys.
