Are you sure they made SA daggers? From what I know HACO was a distributor of any kind of military equipment and supplier of the SA Gruppe Berlin-Brandenburg. The full name of company is HACO-Werk & HACO Transport GmbH, Berlin located at G�terbahnhof (freight depot) Halensee.
I.m.h.o. it has nothing to do with "Hacompa" firm from Solingen, who actually made knives, but never used HACO as their brand name.
HACO daggers have some similar features to Th�ringen made daggers, and because the region of Thuringia is much much closer than Solingen it could be reasonable for Berlin based company to get the products there.
There is also another Berlin company name to found etched on the (NPEA)blades - Karl Burgsm�ller, and it's known for 100% that Karl Burgsm�ller was just a distributor. I believe it's the same with HACO.
