Chris Brooke's excellent site The Virtual Stoa has pictures of Lucy's engineering plant, in Jericho in Oxford, now rapidly in demise, as it waits to be sold off: for more high-price housing, I presume. 

Between 1992 and 1995, I used to stand outside the plant for many weeks, sporadically selling Socialist Worker. Friends tell stories about one time when we were there and I heard a dog barking, which was enough to make me cower: it turned out to be just a pooch. 

By the end of the 1990s, I knew many of the stewards there, including one who had a lucrative second career as a band manager. Friends wrote SW workplace bulletins, eventually depositing a run of them in the Oxford library, where there was already a long run of Lucy's bulletins, the previous incarnation having been written by members of the Communist Party as far back as the 1930s.
