Hey Bugsy wish I could point you to appropriate website ~ surely another ’cat will help out. I repaired a harp several years back, and yes! all the bits & pieces ARE out there. Counting on a harp-friendly to pick up this thread. I distinctly recall a site that was precisely what I needed to bring an old Oscar back to snuff. I’ll check back here to see if you’ve found info & material, & happy strumming!
