Yes, interesting steel type stamp w/ the dots fore & aft along w/ the block Gs on most components. I believe the Gustloff Werke Suhl( Berlin-Suhler-Waffen- und Fahrzeugwerke Simson & Co.)either was a part of the Sachsengruppe(konsortium??) or had Sachsengruppe groups to source from. I'm sure the tubes were completed in Suhl but I wonder if they were rolled in Suhl or sourced from Liege or another member of the Sachsengruppe?
