Have obtained a wooden hull no. 2948 thought to be a Winder design, but other than that can find no further details.  It has been buried at the back of boat shed in the Lake District for 10 years.  Any details such as age, name, builder etc. would be most appreciated.  Many thanks in anticipation.

Built 1975 by Guy Winder, to his Winder Box design, called "Winder Box" so presumably the first to that design.

That's great.  Can now try to track down original photos in order to repair correctly.  Thanks very much for your prompt reply.
