I have a really pretty, vintage one-eared headstall with silver conchos and silver bars on the cheeks. On one of the cheek pieces today, as I was changing the bit, the part of the chicago screw that is attached to the silver broke off (I think maybe I overtightened the screw in my worry about them coming undone while riding
) Does anybody know where you would send something like this to be repaired? Is it something I could fix myself with a soldering iron? Help!
