If you've got any of these things floating around your garden, shed, garden shed or that drawer in your kitchen where you keep all the junk and which never opens properly - then I'd be very interested to hear from you. They are GPO standard ceramic terminators and they're slowly disappearing from the wild.
My restoration project has stalled slightly because I have two of these insulators in a very poor condition. They have clearly broken in the past and some long-forgotten GPO engineer has glued them back together - araldite probably or perhaps a half-chewed Werther's Original.
Anyway, I can't get them off the retaining bolts and so am seeking replacements. There are some spare ones sitting on a disused pole not half a mile from my house. But alas they're just out of my reach.

I now require 3 insulators. My wife broke one after I had left them in the sink to soak along with the breakfast dishes. I have to wonder if she's as 100% committed to this as I am - she wasn't even sobbing uncontrollably when she told me!
