Swiss Sunburst and a Mauser Banner

[mrerick]

Well, Don't assume that all the parts were newly made by Mauser at the time the pistol was assembled and tested for their Swiss contract.

There was likely quite a bit assembled out of sequence for commercial contracts during the war as "special" work that took second priority behind the huge government military contracts.

It's quite possible that a pre-1938 frame was used which had no "ears"... and a long frame originally from DWM would not be expected to have them either.

When master gunsmith August Weiss transported the tooling and gauges from DWM Berlin to Mauser in Oberndorf, the trains also carried a number of spare parts and incomplete firearms. IIRC an inventory was discovered documenting some of this. These parts could have come from that cache.
