[Hallicrafters] WTB: S-72 or S-72L knobs

[SX-25]

Looking to buy four (or more) knobs for the Hallicrafters S-72 or S-72L portable
receiver. These knobs are made of plastic and are 0.93-inch in diameter, 0.45-inch
high and are maroon or brownish in color. The knob is molded with 15 finger indentations
surrounding it and is slips on a serrated shaft (as opposed to using a set screw...although if
you have some that otherwise match my description I would be interested in the set-screw
version).

Thanks!
