To me this looks like a gun that has recently been completely rebuilt, including restocking, reblueing, CCH( not a torch job), and engraving. I believe in the process, the markings on the barrel flats were removed. These markings would have shown the age, maybe the maker, proofing, whether it was choked or not, caliber( gauge), chamber length, and bore diameters. The "Repair" proof on the water table leads to the question, what substantial repair was required? Assuming the barrels were not bored out too much, it is a nice hunting gun, but whether it is a "between the wars" Sauer or even a Sauer doesn't matter any more. It is no longer what it was, it now what it is.
