This certainly looks very similar... Thank you.
Strangely it has Swedish 3 crown roundels on it and just speaking to a someone at Howes in Oxford, he mentioned that it might have been built by a builder in Reading although he couldn't remember his name...?
Thanks John, John & Eric. I don't think the mast prebend is a problem, in fact there is quite a lot of backstay tension to get the mast straight or should I say to match the luff in the main sail. This in turn actually pushes the centre of the mast forward and in doing so brings the spreaders closer to the topping lift I shall have a look at John Bennett's boat on Friday and try some elastic. I have some 1.5 mm elastic which may do.
Thanks for all your advice. Michael.
