Thanks tsmgguy, I added it to the study. I do not know a great deal about these either, only what is in the books most of us have, - you should think about getting Storz book on the subject if it does become a fascination. The book is far more than a dry study on the rifles, the books goes into great detail about the history and men/companies behind them. It is far superior to his Modell98 book, and probably better than his Modell88 book. The translations are certainly better... personally I think they used google translates for the first book (Modell98), it has a deplorable translation, which is unjustified because many Germans are highly skilled in English, - probably the only good thing to come out of WWII.
For the data base:
Spandau I.G. Mod 71/84, 1887, sn. 1085.
This rifle seems to be unit marked on the top tang of the butt plate. These markings read:
24. R.E.
2.56.
I know little about these rifles and bought this one because of its original excellent, unissued new condition. I don't think that it's ever been disassembled or fired. All serial numbers match, down to the bolt heads.
