Well, back in the early 80's I worked for Games workshop in the Manchester store... it was a great time to be collecting lead and I was literally like a kid on a candy store... I was in charge of miniatures and built a good relationship with a certain John Stallard who was in trade sales at the time. I discovered Shot Tower Studios through (I think) a White Dwarf ad and got permission to order them in for the store. They were never big sellers (except when we put them on clearance once the shop started more to the 'Citadel' only and in blisters times) but they were lovely pieces, drop cast and lacking in quality on any human figures but the diorama pieces were lovely and I only wish I'd kept the listing that I ordered from... I chatted to the owner and sculptor, Jim Dendy, regularly for the few months we stocked them and, as per the listing, wish I could remember those conversions! Lots of the sets had moving parts and some were quite intricate such as the secret trap in the staircase. A French hobby friend has written a booklet on the company and background and will hopefully publish it at some point. It does make great reading. In the meantime here are my pics from over time (a couple off various sources and all kudos to them including the wonderful Karl Tebb). A lot of the pieces were engraved on the rear with Jim's name and some details.
