I just got hold of a WS 19 MK II. I believe it was never used because there are no marks anywhere from mounting hardware and the wire harness ring teminals have no marks where they would have been connected to terminal studs. My question is what is the transmitted bandwidth? I am ready to put it on the air but am afraid of transmitting outside the top of 40. This radio has been in an attic since the 1940s. The serial numbers match on the radio, power supply and the variometer. Thanks for reading, AJ8L.

Do you own a serviceable 19 Set? Yes
