Um, yes the Department store(or importer probably) as typical did not want any names or marks to point to an actual maker. Although on the frame somewhere on under the buttplate might be a clue.

I would want to say that that powder test advertising ceased around WWI and for sure after WWI all this price-point importing from Belgium ceased and makers, dealers, whatever in the U.S. of A. had to source locally.
