Any idea where to get my hands on an old hover mower in the UK?

Hi, I used my Gran-dad's old Black & Decker hover mower for 12 years until it gave up the ghost and then, a first generation hover mower I found in my uncle's shed, which has, unfortunately just packed up. I prefer the old 1980's hover mowers, especially since B&D stopped making a hover. I prefer the old metal types that don't have grass collection boxes and the whole thing hovers, unlike most of the Flymo range apart from 2 or 3 of their models that are noisy and plastic and tend to overheat the engine, Any ideas would be gratefully appreciated, thanks.
