Another example of "name" and "noname" Mausers:
Some time ago this rifle was sold through egun. Barrel signed by "Joseph Lang & Sons, 102 New Bond Street, London". Not really a big name, but at least a London address and London proofs. Pre-WW1 DWM action. 27" barrel in .375 Rimless NE aka 9.5x57 Mannlicher – Schoenauer.

At about the same time I bought this noname Mauser, a near twin. Same London proofs, same DWM action, same barrel length, same .375 Rimless NE chambering, same style of sight bases, same stock shape. Only about 10% of the price.

IMHO both rifles, name and noname, were built by the same men in the same shop.
