At the Rotary Club's annual charity sale today I bought a Computrol bulk film loader for £0.50
I don't see myself ever bulk loading my own film so it is free to anyone who wants it for the cost of the postage. Probably not worth the bother to anyone outside the UK though.
There are no cartridges but it seems complete and in working condition.
It came with some film in it. Unfortunately, I didn't know that when I opened it up! I will keep it for fixer testing.
