It must had been an awful lot of work to produce this rifle, and the guy who did it was good at doing it. But he of course did some errors.
- The elevation ring on the scope is not as it should be. Why?
- Ajack scopes in turret mounts had a long rainshield in place. This scope doesn't, it has the short housing. Possibly the focal adjustment ring was removed and hidden behind the rear turret ring. Usually turret mounted Ajack scopes would have a small focal fixture screw on bottom - this one doesn't. Also note the Ajack scopes are always soldered that way in turret rings that the front ring is at the very front position where it could be - with this scope it isn't.
- Stock serial number on bottom is overstamped, you can see the original serial number below
- receiver serial is with a capital suffix. If it were original, it should have a lowercase suffix
- late BYF rifles to my knowledge only had the last two digits on the cocking piece/firing pin locking thingie ... whatever you call that in English, the part at the very end of the bolt
- I don't know the scope serial, but already with that it should be able to tell whether it's correct for a late HT rifle (as it should resemble with all the stamped and welded parts and the late Kriegsmodell-stock), or incorrect
I think most people were assuming from the late features that this rifle should be a HT rifle. If I'm seeing it correctly the front base has a stopping plate screw, therefore the front base appears to be an original LT base. This on the other hand - especially with all the late features - would be incorrect for the at least 1944 dating rifle.
Also note the fonts on the serial number are different on the metal parts. While on the barrel band and magazine floorplate it has serifs, on the bolt and receiver it doesn't have serifs.
