Stan:

What was the tube steel type & did it have Simson in script on the underside of the tubes? 1952 was about the time when quality hit bottom and there was a threat of revolt by the mechanics in Suhl if quality components were not supplied to said mechanics. This is when the 4 Ringe Russian 50A arrived. Post WWII till after this dip biased the masses to described the wares of Suhl to be inferior and the Quality Seals arrived on the scene. Could be a shooter or could be something akin to Otto Reif's wares.

Cheers,
