Odal and I have been looking into this exact thing,,,the laws concerning this stuff!
Seems like they were deadly serious right around 1933,,,but for some odd reason there wasn't any enforcement.. Probably because it would have been almost impossible to enforce.
I think by the time the war started they basically just gave up and let be.... BUT, there might have been years before / or shortly after 1933 that there was a under the table understanding that jewelers and retails might have 'donated' some cash to the party for the no enforcement of the laws. [?]
We've found some laws,,but as I mentioned,,there wasn't enforcement.........
