Chuck,
I have a couple of vintage instruments. I played in a couple of bluegrass bands in HS and College. One is a 1920 Gibson F4 mandolin that is likely one of the finest examples on the planet and a 1931 Martin OM-18 guitar. There is ony one place that I take them for repair. Mark Simon of Simon Guitars. He is in Bridgewater, NJ. I think you know where that is. He is one of the very best you will find anywhere. Not just my opinion.
