I sold mine last year on Ebay and it made £475, i.e. the starting bid price because there wasn’t much interest despite it being the rarer two-speed version.
I have a workshop and garage full of classic British machine tools, mostly in very good condition, which I thought were somewhat of an investment when I bought them. However, I now think they are becoming more of a millstone round my neck with the time to downsize, or the need to relieve my wife of the problem should something happen to me, fast approaching.
I think this is because of several factors: a. there is diminution of interest in the hobby generally as the older generation recedes, b. the younger element that exists is increasingly interested in modern technology with CAD, CNC machining and precision laser cut parts becoming commonplace and c. as the old British machines change hands over the years, becoming increasingly worn, they are more conveniently replaced by new far-eastern products of which the quality, price and availability makes them a very attractive proposition.
