15 Kc (!) to 600. In those days, LF was the main band for ships.

For some reason, when these things were decommissioned they obscured the nameplate. But on this one, it looks like they just went through the motions. It seems to reveal a brass panel, nickel plated. In the cabinet on shocks.

I have had this operating... VLF via a signal gen. and the low end of the BC Band with an antenna. Hi res photos if you want, but very clean inside. $125 plus shipping (maybe 20 pounds or so).

Thanks
