I was a member of the UK Activity Club for as long as it was running (1986-1991) and am lucky enough to still have most of the newsletters, special items, etc.
I'll attempt to list as much information as I can, which I help will be useful for those trying to identify Club items, or interested in finding out about the history of the club in general. I can't guarantee an absolutely complete guide, but I shall do my best!
A few scans of things may be added at some point - we shall see!
