This magazine is produced by Walther as can be seen by the welding spots and is very interested because it lacks any stamps on the left side of the housing. The Walther acceptance stamp E/359 is stamped on the spine and this is the only marking present on the magazine. It is not sure why the P.38 markings is omitted but it is believed to be a production error. Internal parts are also not stamped with E/359 and this indicates that the magazine was produced after March 1942.
