Antique telephone insulators

These come in a huge number of colors and shapes. I can remember walking under telephone lines that had been updated and looking for the insulators. I have a few somewhere.
Today has been another very low key day with me not stepping a foot outside. I still don't feel well but not horrible enough to stay home. I have a mask at school I can wear.
The extra is a photo of what the lines used to look like. Did they use these in the UK?
