[Hallicrafters] Need Knob For SX-96, 99, 100 or S-85 or S-86

[W9zr at aol.com]

I am looking for the larger bandspread tuning knob used on the SX-96, 99, 100 
and S-85 and S-86.  It is 1.5 inch diameter and the metal insert has a slight 
rise in the center.  It may have been used on other receivers too.

I need it to complete a project so any help would be appreciated.
