Too, LIndner's could have accompanied Sauer's wares that were either sent or inspected in the shop. So Lindner's could have been a part of a whole that was submitted for Vorratszeichen. I just do not recall any of Lindner's wares that wasn't submitted for proof when proof was law. Daly didn't spent the money for the voluntary semi-smokeless proof until it was required post 1912.
