Sonora brand?

[Eric H]

One of the four sets I picked up last weekend was a 12" Sonora model 302, I was just curious if anyone had any history on this company?

It has one unique feature, a continious tuner, or at least a non-detent tuner with a weird, oddly numbered knob.

It uses a multi gang tuning cap with a mechanical switch that clicks over when you go from channel 6 to channel 13 to accomodate the frequency jump.

Here's a pic of the knob, kinda cool
