Thorn LUD R1065 Invincible

Thorns Mk1 Invincible batten is very distinguishable by its compact construction, and the 6 bowl clips matching that of the Mk2 Thorn Alpha 8. Later ones would see these bowl clips widened by a very considerable amount.
This was salvaged along with a few others by a fellow collector from a petrol station. Upon arrival it was absolutely plastered in years of grime. Apparently this was the only one worth having as the rest were badly damaged. Even so this one still has a small hole in the cover.
