It would seem that the Sauer ledger is akin to Bigfoot/Yeti as many have seen it but few, if any, can provide specifics. But we do know it exists & where it is kept: in the old Suhl jail basement. Sauer Nr. 222250 is given as a V,L, & D Modell Nr. 280, similar to an 8E, as described in Cate's Sauer text so I'd say yours was lumped in a ground of V,L&D and wasn't badged for some reason? It still could easily be a S,D&G variety also. I really haven't any idea on the V,L&D modells.
Again w/ the stamps in English, me thinks a pigeon version is really a red herring. 1st Lindner developed the 56mm frame & when the A&D Body Action protection period expired, then Sauer adopted the platform and who better than Lindner to lend quality control?
Cheers,
