Made in the mid 1980's by Bob Mendelsohn. Custom "Ricker" knobs. When I first made them I had a wooden dowel running the whole length but then I removed that and only used about a 2 inch section of dowel to hold the screws for the knobs.
27 inches long, 4.5 inch diameter. 280 grams or just under 9.9 ounces.
Shown here with a Todd Smith American for size comparison.
