I opted not to post this in the Basement and post in the General Area as I have exhausted all possible sources.

I have been admiring a Joh. Springer's Erben 1922 Biks that has Krupp tubes by Stephan Schilling & more than likely was made by Morgenstern of Weipert, as were almost all of Springer's Erben's offerings in this platform.

Anyone have any idea of what the 2 holes in the right side of the forend wood might accommodate?
