Its a Boots Super Deluxe 8.
I've been lent it to transfer a film of St Mary's School 1967 to DVD but the projector side wasn't secured properly so I took a snap before fitting it back on.
Normally you would be expected to change the bulb or to replace the drive belt that snapped more times than I had hot dinners.
Took me a while to thread it. The film was all jumpy and I remembered that the film had to have a loop before the heel or this would happen.
I haven't played with one of these for 30 years
