Thank you everyone for the replies. I did find another photo of the 7x57, and the receiver is stamped Deutsche Waffen und Munitions Fabriken - Berlin

Can anyone make a strong estimate of the produciton date?

The 9.3 depicted in my photo is stamped: Made in Austria , Original Mannlicher Schonauer, Model 1950 9,3x62”

Also, I have some Jeffery Rifles that are atamped with the following address. Does anyone know what time period Jeffery was located there, and by assumption, when the rifles were made?

The address: WJ Jeffery & Co Ltd, 9 Golden Square , Regent Str, London W1

Also have a Mauser Action with the following stamp on the receiver. Can anyone tell me the manufacture era of the rilfe?

Deutsche Waffen und Mintions Fabriken – Oberndorf.

Also a Cogswell & Harrison with this address:

Cogswell & Harrison Ltd London, 168 Picadilly. Supplied by TJ Goldings (PVT) Ltd, Gatooma.

presumably made in 1950?

Many thanks-
