Hi Clockmanbill,
Pretty sure most the German movements from the mid seventies through the 80s went with the plated pivots. Guessing on the dates here.
I think Mark Butterworth had a list on his site?
I’ll check,
Bob
edit: I’m not seeing anything on the Butterworth site so I got that wrong. I did see something about it somewhere and thought it had something to do with him but just can’t remember for sure. Anyone??
