This should probably be in the 1933-45 section, but due to the 98m connection I am placing it here.
It's an import, so the only important points are the barrel/receiver markings, which is the odd part- there are absolutely no other markings on the barrel than those pictured, either fore or aft of the sight base. There is a small 7,91 caliber designation at the top of the collar, thats it! Sight base is marked e/77 3 times, but the early Erma style inspection. I don't believe the "S" is part of the serial, but rather like the "S" marked on Gew98 barrels.
