I've got old German scope that I can't figure out how to put on a rifle. It has integrated dovetail, which apparently goes into dedicated mount. The tube is 28 mm in diameter, so no rings will work. It also does not have windage adjust., only elevation. The clarity is excellent, perhaps the glass is made by Zeiss or Leitz. I wanted to put on my Swiss K31. Please advise if you know if you know how to mount these scopes. Thank you
