I have a pair that work and have been restored. I won't be needing them and will sell them as I found NOS ones on Ebay. Send me a PM if interested. I saw some on Ebay not too long ago and will look for them and send the link. I got mine to work by setting up the charcoal grill. After my steak dinner, I placed the cable in the coals. The rust was converted to a dust of sorts and came free with no effort.
