A difficult to pin down range this, far more seem to have been sculpted than were ever advertized, and collecting them all is a lifelong (and beyond) task, if you can keep your sanity...
There were certainly 2 batches or releases, in 1985 and 1987. I also include the 4 character pieces from the Curse of the Mummy's Tomb set and the 2 LE3 Gumshoes.
If you have more, send me a front and back shot, and I'll add them to the gallery.  A black background would be nice.
Apparently I'm looking for the 1987 Vicar, if he isn't the Mummy's Tomb guy, and the variant on the Deb with flowers in her hat!
