It had 10 presets?
I found a Farnsworth Console from 1940 with 6 presets at an Antique Show. Four had call letters on the buttons. WKZO, WGN, No Tab, WBBM, No Tab, WOOD. The sixth preset has an open lead, you occasionally hear some unidentified SW activity, from the slight series Capacitance of the open gap. There's some bad trimmer capacitors which heat up and open, and shift the oscillator frequency. I suspect that the third preset had WJR, and the fifth had WLS. I told the Antique Dealer the radio was from near Grand Rapids. He was very impressed. Maybe they later set the other buttons to WJEF and WLAV and removed the call letter tabs.
