I would appreciate any input from anyone familiar with Kays. I went to look at one tonight. It is about 50 years old, and has seen alot of use. The body has lots of scrapes and scratches, but no serious cracks. I looked inside and couls see the Kay label and the serial #, and also the number "M1", which I assume is the model. What else should I be looking for? The gent that played it played it in a Hungarian Gyspsy trio in restaurants, and just used the bow. The action is incredibly high, and the bass still has gut strings on it. It will need to put a new bridge on it, what should I expect to pay for that? Also, what about the fingerboard, is there anything I will need to do to see whether or not I will have to have it planed?
