Guess the boat manufacturer??

[Murfanator]

Hi
I have purchased a 24ft trailer sailor as a project and I would like to know who was the original manufacturer if anyone can help? I believe that the year of manufacture is around 1975 but there are no identification plates on the boat. I have had a look around at various bow and stern angles and window shapes / positioning (I know these can change if you really wanted to) but I can not seem to find a similar model. Any help would be much appreciated.

PS So far I have only serviced the trailer, emptied the boat, gave her a good inspection and stripped the electrics and the roof lining but I will get there
