In Germany what would have been the standard chamber lengths for a 16 gauge made in 1939?

If not stamped 70mm on the tubes or 70mm on the extractor face, the chambers by default would be 65mm.

If they were made for export to the US, I've also seen them marked 2 3/4 on the extractor face.

This was correct till recently when extractor faces with >>70<< have surfaced. I can post a foto if need be.
