Are you quite certain that the KKs aren't to RRs from Roe
Römerwerke¿ I haven't seen exactly that on components out of Römerwerke/Rhöemerwerke but I have seen a double R with a Sword thru them on a 1925(June 10th) Römerpistolenbuechse advert in Der Waffenschmied. Now, I have no idea on the Suetterlin Style mind you.
