Yes, older model Cbobs had blued bushings and hammers. My PT-C is a 2005. Mine is made from pre-CZ and CZ DW parts. It came with the blued bushing and hammer, as well as the DW Patriot logo with the circle of stars and the Cross above the Patriot and the DW. I will never ever sell this pistol because of that.
When I first got it
I've since had the bushing replaced with an EGW thick bushing and plug.
