Hi, I've seen two styles of brass Chickering hammer flanges - one-piece with bushings and no drop screw (there are wooden versions, too) and two-piece clamping, but in a more usual arrangement. I've never seen failure in either of these (except the poorly engineered wooden ones), though their brass wippen flanges seem always to break at the slot. Let me know which kind you need. Regards, Clark
