Here is another great go-with! A black lineman's test set phone with rotary dial -- it has the large clips to attach to the wires. Just a small chip on the rim around the dial -- $75 plus actual postage.

NOTE: I'm selling these insulators on behalf of the Jim Fielding estate -- PayPal (no fee friends and family) or checks are both accepted - I'll provide instructions. I'll also be handling all the packing and mailing.
