Sounds like a novel idea.

Too, the key is to discern if a German gun passed thru the Suhl proof facility or the Zella-Mehlis proof facility to point towards its origin. Now there was another proof facility but one gunmaker had it under his umbrella and he was about only one that submitted there. But the makers of Suhl considered the mechanics in Z-M >>Red Headed Step Children<<, but they did source them when they wanted to increase their profits. When a Suhl mechanic would make an error or churn out shotty work, they would say it was >>Zella-Mehlis<< quality work. When a water-table was jeweled or the like, the Suhl mechanics would say that was >>Zella-Mehlis<< effort to cover up shotty work.
