The Simson family had the misfortune of being, Jewish, during WWII. At the end of WWII, the East Germans continued production of the Geco, Simson, Merkel, and some Sauers, in the old Merkel factory. The actual firm of J.P. Sauer had moved to West Germany, but that didn't stop the East Germans from producing Sauers as well. The cosmetics were'nt the best, the sngraving, fit, and checkering wasn't as fine as the older guns were. For the most part, these guns were built like bank vaults. Underlugs, crossbolts, sideclips. I wouldn't worry about chamber pressures, that is, AFTER, a competent smith has checked it out. Old guns, regardless of reputation, should be examined on a caes by case basis.
Good luck with it.
