If I see something helpful in print I copy it and file it away. I hope this will be of use to anybody interested.
Great stuff there. But I have a question, I have a banjo that the center is 3a 13/16. The backing plate mounting surface is 53 inches which according to this points to a 42-48. But the distance on my spring hangers is 48 1/2 which points to a 35-40. Anyone got a clue as to what year this is?
