I’ve got a vintage steel buttplate, at least 100 years old, that I’m going to re-purpose on a rifle. I need two custom screws to secure it. I’d like to send the buttplate to the gunsmith/machinist for the work so they can match the countersink appropriately. I’d also like the screw heads left long so when the final install is done the smith can index the screw slots. I appreciate any suggestions for a good person to do this work.
