Looks more like 1948 then 1958! was amazing to see all those E52 and KwEa receivers, don’t know if it’s true or not but recall seeing somewhere that the E52 was in production post war and used by several state agencies in west Germany.
Both receivers are something that I would love to own and play around with but unless I win the lottery don’t see that in the cards. Did have a Torn E b for a while and had lots of fun playing around with that.
