I am trying to restore an old 5-string, open back, banjo I found in my parents' attic. It has a brass plaque on it that says Dulcetta BS London, which leads me to believe it was made by Barnett Samuel in London, England in the early 1900's. They also sold banjos under the name John Grey and Sons. I need a new head for it. It is 10-7/8" diam but I can't figure out the crown height. Is there a way to find this out (the company is long since gone)? Or is there a way to work it out? Or should i just order a medium and see how it fits?
A medium head should work. Here's Stewmac's advice: https://www.stewmac.com/Hardware_and_Parts/All_Hardware_and_Parts_by_Instrument/Banjo_Parts/Banjo_Heads/Five-Star_Banjo_Head_White_Coated.html
The best way is to measure the heighth of the tension hoop. If there is no cut-out in the hoop where the neck goes then the crown heighth should be at least as tall as the hoop. If there is a cut-out where the neck goes then the crown heighth should be at least as tall as the cut-out.
Use the smallest heighth head that clears the measurements described above.
Of course, this assumes that the end of the finger board is level with the top of pot.
That's great info. There is no cut-out for the strings and the tension hoop is 7/16" . The finger board is indeed flush with the top of the pot (or it will be when I restore it). So I'm going to go with a medium crown.
Thanks for your help.
