This pot is unmarked as far as I can see but is certainly well made. The rim is tapered toward the top (head) with a 'Little Wonder' type tone ring.
It's tough to see on a 2-D picture, but that dark part of the rim is tapered down to the width of the LW size tone ring.
Diameter?
# of hooks?
Twenty
Twenty-bracket banjos were usually made in Chicago. Slingerland, Kay, Lyon & Healy, and Harmony come to mind first. Measure the diameter of the rim at the bottom. Slingerland used 10 3/4" rims and early Kay banjos used 10 7/8" rims although the features of this rim don't look like either one of those builders to me.
The rim measures 12 1/8 inches diameter
