I have a couple of Simplex sets that are similar. 4 tube trf the tricky thing is the the knob on the right is for a tone control and band switch. The sw band is not calibrated on the dial. Same tube layout, uses the fc in the negative leg of the hv to make the bias for the 47 w/a couple of resistor in parallel w/the coil.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
