The rifle pictured is all matching with the exception of the bolt, which is a Czech replacement. Oddly, it has about 95% original finish with polished receiver, butt plate bolt and cleaning rod with rust blued barrel jacket and trigger guard and barrel jacket. The bands are niter blued.
It
is marked to the 73rd Reserve Regiment (1st Hannover Reserve)
and appears to have never been issued after the conversion to the 88/05 configuration, not even by the Turks! The rear sight has been re-marked in Turkish and it has a Czech bolt, as many Turks do. The bore is perfect and the T.P. Hern has stated that he has never fired the rifle and probably never will because of it's nice condition.
This rather odd marking on the rear of the barrel jacket
at the receiver ring (F over W over W) is, according to Karl-Heinz Wrobel, an
importer mark indicating post WW2 import into Germany by Frankonia Jagd.
Apparently, this one was imported into Germany and then came to th e United
States at a later date. John Wall, John Sheehan, and T.P. Hern originally
thought that the FWW marking could have been an Austrian marking indicating that
this rifle might have been an Austro-Hungarian M13 rifle (Gew88 given by Germany
to her WWI ally) buy Karl-Heinz cleared that up nicely for them. Still, a neat
marking not often seen. T.P. Hern also mentioned the 8X57J marking directly
under the "FWW" should have been a clue that it was a civilian
marking. But sometimes the obvious doesn't bite you in the face the way it
should. There is also a marking on the barrel jacket in front of the swell where
it attached to the receiver that says "8MM" that is barely in the
picture
above.

And a big thank you to T.P. Hern for providing all the above pictures and information.
