Maybe a mod should make a separate thread for your scoped G.33/40.
The rail on your rifle is a weird basement job which is waaaay to high, compared to an original. It lifts the whole mount much higher than it should sit, if it was original. The mount also does not look original to me, more like a modified reproduction. Finally the scope, in that serial range it should be marked SS Dienstglas. I actually though don't believe it was one, there is no rifle serial on tube either. So as a final conclusion, someone killed a rather nice G.33/40 to equip it with a scope which actually isn't what it wants to appear.
Edit: just to be clear, there weren't G.33/40 sniper rifles anyway. Yours though doesn't even use original German WWII parts, but is made of various reproduction and commercial stuff placed on an original G.33/40 rifle.
I would love if a moderator made a seperate thread on this scoped (albeit post war basement mod

) G-33/40, the rifle is all matching serial and the scope is war issue Ajack4x90
And, yes, I was fully aware the mount is not original and it was not issued in this configuration it being a German Mountain Special forces rifle it neither came issued in this configuration, nor was it a field modification by the German soldier, it was added later on when someone tried to fake the mount being issued with the rifle...probably an attempt to raise the value...even knowing this as I knew the rifle and the scope were both authentic I jumped on it.
This is my first "K-98" and I love that it is unique in a certain way...and I don't see it as "killed" at all since it was never intended by me to be a safe Queen and be sold for profit later on. I have a "bucket list" where I intend to build a shadow box from bullet rated glass recessed into a wall in my office where I can back light four scenes one from each belligerent in WWII, Us, Germany, Japan, and Italy (no France since face it they surrendered and folded out of the gate

) and I intend to get a rifle and a pistol from each country to stand up right flanked by black and white battle scenes and maps or regional conflict, I had thought the M1 Garand would be the next one I would acquire, yet fate would have it be the G-33/40. Once I get it home I will post a plethora of photos on it so I can benefit from the "brain trust" hereon. I would love to find the service history of this rifle and scope, at least where they were issued, perhaps a validation of the serial # can be a good first bread crumb. On my bucket list I have already gotten a 1953 Tokarev and a 1963 PPH-43C, yes, from a later era, not war time, but both are the exacr model issued, and I have an SKS, but want a Mosin Nagant instead to go in the box...I intend for an Asikara 99 and a Nambu to fill out my Japan section.
