Just seen this one on Ebay:

Apart from needing a varnish job on the foredeck it looks to be in pretty good nick! She's 3148, named 'Hemlock', a GW Winder 'Disguys' design. Please, someone grab it before it gets stripped and burned...

This boat was 3rd in the 1979 Champs, sailed by Graham Pike.  A Disguys also won the inlands that year sailed by Robert Harris.

Went for £365!
