Hello Gerrit1963, there is not the least doubt that Ch.A.W. is the mark of Chromolit Arthur Wingen even more as it is the serious research product of the most experienced but sadly late A. Carter AND (local!!! - I think at least these should know exactly) Solingen swordsmiths which was published in full version a few years ago.
The fact that the "ch" is looking differet on the invoice and on the knife imho says nothing because the use of totally different fonts for one and the same during the period is not uncommon.
But nevertheless thank you very much for showing this interesting invoice!
Btw I do own a period studio wearing pic of a member of the Forstschutzkommando. You can clearly see what sidearm he is wearing. A stag horn gripped walking out bayonet..... unfortunately no Waffen Loesche.
Regards,
