Chris,
You are correct, BKIW was essentially DWM with a new name, so the real change is the end of one era and the beginning of another.
BKIW continued the use of the DWM toggle marking (even Mauser and Krieghoff used some DWM marked toggles).
There was nothing â??sneakâ? about initial BKIW production. The Lugers produced are what we call â??1920 Commercialsâ? and the guns permitted under the treaty of Versailles for military and police use. The so-called â??sneakâ? Lugers were later production ca. 1929 or so. Joop van de Kant is doing some research that suggests these sneak Lugers were taken, at least in part, from the aborted Riff contract that were prohibited from delivery by the German government and later sold to the Reichswehr in the early â??30s.
P.S. I was a little slow in my reply so I apologize for any redundancy with what Dwight posted
