Thorn PP265 Pop pack

Featuring a prismatic diffuser.
I was given a lead by a good friend of mine that his brother had 2 of these in his shed somewhere, and that I can have them. A few weeks later, we went to collect them. I was told that they were removed in 1981, after just a few weeks service, and then declined into a absolutely terrible state while in storage on a damp, soil floor with absolutely nothing to protect them. As such both ends of the spine have now become extremely thin. I restored them and then installed them in my shed, but in more recent times, I had to remove them due to severe damp, once again rusting these, and other fittings in the shed. I plan a full restoration once again, and hopefully they'll turn out even better than what they did this time round.
