They are not worth much in terms of dollars - but collectors like them. If
I see them at a swap meet for under $10 and they are in good shape, I often
buy them - simply to keep them from being trashed.

I have converted one into a solid state heterodyne vfo for a Central
Electronics 10B and converted one into a very nice regenerative receiver.
It has a good range of parts for the regen, including a very high impedance
audio choke and a wonderful tuning assembly.

They are still light enough to ship at a reasonable price. Do not be too
greedy on price and you should fine a happy home for it.
