Canadian Rogers / Phillips knobs
 

Hello, I am in need of one of the smaller "inner" knobs for a 1949/50 Rogers Majestic / Phillips television. I can't believe this style of knobs were used exclusively on these sets. Wondering if they are identical to knobs used on American television sets. Anyone know of a U.S. brand that used this style, so I can refine my search. The smaller knob has a 3/16" shaft size and takes a set screw. The large tuning knob has the 2 -13 channel numbers molded into the Bakelite (not shown here). I've posted this over at antiqueradios as well.
