Rangehound,

I am trying to visualize what you are describing. I am picturing that you have a partial serial number stamped in the sling well vis-a-vis the Bavarian markings? I would look very closely at the area under different light angles. I have a beautiful Trimble NPM stock with the partial serial stamped. The Germanicon's chiseled the "Trimble" off to stamp the serial and it is barely visable with strong light at a close angle.

Pictures would help in understanding exactly what you got.
