I think, sometimes German’s craftsman had factory in Germany but offices in USA. 1937 it was nazi time in Germany and some craftsman moved bissnes to USA. First step offices and secend letter factory. Sometimes it was taxes staff. Finally on the razors tang is SOLINGEN Made in Germany.
Or my secend thing
1937 German nazi murdered some craftsman, grabed their factory and made goverment, public or statement facory.

What do you think?

Ps. I” m so sorry about my english.
