What is the correct knob for the on/off switch for a Philco 91? My 91 has the same rosette knob that is on the volume and tone controls but I have seen photos on-line of other model 91s that have a smaller rosette type knob.

Late production 91 sets used the medium rosette on the off-on switch as well as the volume and tone controls. The 91 I currently have came with three medium rosettes and a large rosette for tuning.
