Just when I was excited to find one, after searching for years; another one falls in my lap. Found it at an auction in a tiny town in Illinois. Pretty dirty, but cleaned up and proudly sitting next to the other!

The new one is missing the little red on/off knob on the left. Still gotta find that!

If you decide 2 is too many for you, I might be interested in one.

Thanks to ElectronicM, my first set is now complete and has its missing channel selector escutcheon/knob! Thanks again! Now to find the small red on/off knob for the second and they'll both be complete.
