Hi LARRYW
I am certain this is an A Class hull ,by a strange coincidence a week before Christmas I was given an identical hull that was on its way to the tip ,no history with it ,yours has some not very clear letters on the hull so could have a racing history that could be traced if it had been registered ,I know nothing about sailing but love the lines of the boat so like you I am going to restore it ,I went on to the Vintage Model Yacht Group web site and if you send pics.there is a chap on there who can identify yachts going back years ,I am fotunate to live not far from where they sail so will be able to go and get some info first hand but try the web site you will find it interesting.
