Hi @mrlwalmsley, welcome to the site.
That boat has the look of a very early Explorer Elite. The square top of the cuddy and the front/side windows look similar. However, the hull doesn't have simulated clinkers like the Elites do, and the splashwell design is different, which is why I say it could be an early (or prototype) version.
What age is the hull? Is there a hull plate anywhere on the boat that gives the year of manufacture?
Nice project though - assuming the floor and transom are sound it'll make a cracking boat once it's refurbed.
