I used these on my 1962 Harmony rebuild. They look and work great.I reccommend these to everyone. Stu-Mac is the greatest!!!!!!!
bought some from china on ebay, they are junk. these are quality, more than china but i can't even use those so i just waisted that money. if you need these, they are a great value.
Too much money for these litte things.
I used a set of these on the bridge of an old Harmony Master Archtop that I was reconditioning. The old thumbwheels had oxidized and pitted and did not function very well. This set put things back into good working order. Simple, but nice.
