[AMRadio] Any thoughts on this Harvey Wells?

[CL in NC]

Can anyone ID this particular transmitter? It does not appear to have a band switch, has a toggle for 'tone', has an aux input with a control. The mounting base is more what you would expect for a vehicle or aircraft. Harvy Wells made an AR-2 aviation receiver, no evidence of a matching transmitter, plus they built police radio gear, could this be something from that line?
