Sorry Dave, but I absolutely disagree. The SS Dienstglas engraving is totally wrong. Hell, the letters aren't even in a row and with different distances to each other. Look at the "a" on the rear! Also the Deaths head, the original ones are nearly round. This Deaths head is higher than thick. Also the scope serial looks suspicious. I tend to vote that at least the digit "4" and the digit "3" were re-engraved. Probably it was an earlier production scope which was re-engraved to be in the SS Dienstglas serial range. Additionally, there is no rifle serial engraved to the scope tube. It should be.
However, the mount looks original to me. If you can, buy the scope mount. The base could be Swedish, would need better pictures.
If you want an original scope, I have a spare one which I'd sell. The "SS Dienstglas" is partially scrubbed, but it's an original one (and scope only). But didn't I once offer it to you?
Attached are some pictures of my complete and original SS Dienstglas. Compare the font and way of inscription and you'll notice the difference.
€dit: funny. Notice that the engraving on the scale ring are exactly in the opposite direction written. Funny. Someone didn't check original ones good enough.
