Made in Germany by Mauser-Werke A.G., Oberndorf a.N., this K98k-pattern short rifle was produced in 1941 and exported under the Portuguese m/937B contract. The receiver ring bears the Portuguese national coat of arms crest and the 1941 date. German military acceptance and inspection marks are present, including the Waffenamt eagle/655 proofs and Reichsadler stamps on the barrel and receiver.
Contract provenance notes document that F-block serial numbers were shipped to Portugal. This example features a PB suffix adjacent to its serial, and multiple matching numbers were observed on the receiver, barrel, bolt components, and rear sight parts. These attributes align with known characteristics of Oberndorf export rifles built for Portuguese service as the m/937B.
The rifle follows standard K98k configuration with a 23.6-inch stepped barrel and a controlled-round-feed, three-lug Mauser 98 action. It uses an internal 5+1 magazine, with a stripper-clip guide integral to the receiver bridge. The bolt has a turned-down handle, and the safety is the three-position wing type.
Furniture and hardware are correct to the pattern: a hardwood stock with side sling slot and keeper, top handguard, H-type front band with bayonet lug, and a buttstock takedown disk. Sights are the classic iron set with a hooded front sight and a tangent rear sight. Metal parts carry a blued finish over a steel receiver, consistent with Oberndorf manufacture and export marking for this contract.
Designated in Portuguese service as m/937B, this WWII-era 1941 rifle combines contract markings, German proofs, and Oberndorf manufacture in a cohesive package. The bore remains clean and shiny with well-defined rifling, supporting its appeal as a clearly marked and well-configured contract K98k.
