I recently inherited this rifle which my grandfather supposedly brought back from WWII. I have been doing a lot of research and have yet to determine the date of the rifle. I have narrowed it down to a Simson sometime between 1925-1931. The strange thing about this 98b is that more of the barrel is exposed than on any other example I have been able to find. Any information on determining the date would be appreciated. Also, i was assuming this was from "d" block based on the cursive d but after looking again I guess it could be an "a". Thoughts? Let me know if I can provide any additional details. There seems to be 2 different serial numbers on this one. The stock, receiver, and barrel all have matching codes. Every other part on the rifle including the bolt has matching codes.
