Nomenclature (?) plate, main tuning knob, vernier tuning knob, dial lock. Anyone have these. Also, how do I tell, exactly, which model/serial number, I have? >From the manual, I know that mine is a relatively late model since is does not have the noise cancelling circuitl. Also, there are NO marks or stamps on the front panel. I suppose the previous owner painted over them. Too bad. Ken W7EKB
