Hi Joe, Try Wally Brooks at a starting point, or Lloyd from Renner. I would love to have a steady supply of Geman Silver pins. The supply house's seem to be hit or miss with their supplier's. The last batch of #21's I ordered were brass with plating. (from a Japanese supplier) I sent them back. The supply house asked what was wrong. When I told them of pin failure due to the plating coming off. I was politely told I was being 'picky", and that it's the first they had heard of problems. Change a set of 15yr old Yamaha underlever pins, and expect to do the job again in 15yrs. I don't think so. Climatical conditions will have a significant effect on how long those plated pins will last. Just some thought's on the topic.
