Dwight, my observations suggest that at least some of those manufactured for the police in 1928-29, after the departure of the IMKK, were originally manufactured with 9-mm barrels. Many of these show absolutely no signs of re-barreling. Apparently, DWM began ignoring the restrictions once there was no enforcement.
