When I was a kid there was lots of Government suplus for sale either through "Army & Navy Stores" or by various firms in Exchange & Mart. I remember by father buying all sorts of things for his garage and for car and radio related projects. Even when I was first in our local motor club we were buying radio masts, shelters, trailers etc from a firm called Proops who advertised in E&M.
I think E&M was killed off by Ebay and the like but presumably there is still government surplus, new and used, so what happens to it? I am sure there is stuff useful for garages, clubs etc.
