Hey mat must have missed this post...
found some links that may help your search for information..
surprised Dicky didn't spot this one...
also see if you can get hold of a copy of Marine Modelling Magazine, September 2003 as it was a big feature in there.
I should also point out that you can buy the hull and cabin from model by design (R.N.L.I. SOLENT LIFEBOAT) for £126 and the fittings set for a further £105... in 1:12 scale. which works out cheaper, but im not sure how much you would have to make up as extra to finish up, suggest a 'conversation' with MBD.
you will need to scroll down just after half way.
