i have a preston english guitar almost refitted and repaired. however my luthier says that the watch key i have for the tuners is too loose. it was the closest i could find at the local watch makers. i was windering if anyone out there knew of a source for vintage or replica watch keys for the prestin tuners, or some one who could make one. alternatively does any one make a complete set of tuners like the prestons? i could replace the old tuners and keep them in the case but use new ones. this is a guitar made in 1747 so its worth resurecting.
