Peter, in the workshop I was responsible for I sold the last shaper around the 1980 ies (to the junk dealer). I had noticed then that shop workers hadn't used it for years by that time. I know it was bought in 1966 from England in a big batch buy to support the government attemptig to save the british pound from decaying. I think the machine was never in action since, apparently, not even the oldest workers knew how to run it. They didn't even use the tools which could have been useful on a lathe, too, because they were very large and sturdy and uneasy to handle.
Shaping is a good thing for working on heavy appliances and had its use in the first half of the 20ieth century. No more after the wars.
