Im missing the Pivot screws for my C# Pinky key, held on with nails right now. I took it to my tech and we tried every screw we could find. Screws off an old Aristocrat Tenor, screws off a Bundy Bari.. no luck. They look the same as normal size Buescher Pivot Screws, but are about 1/4 longer. My Tech wants to use Selmer style pointed pivot screws, but id prefer to use the original kind. Anyone got any suggestions?
