Putting aside the amount of rust, the efforts you had to deploy to strip the paint including the lthographed markings, and open up the shell is an obvious testament to the amazing build (and mechanical) quality of Sutcliffe toys - with almost no part needing replacing!I loved this, not only for the skill shown, but also because, back in the 1950s my parents bought me a similar submarine, a version of this styled on the Nautilus sub from the film “20,000 Leagues under the Sea”, a variation that Sutcliffe made. Hours of fun playing in the water-butt in the garden. I admire your skill and tenacity at fixing what I would regard as ‘hopeless’. Thank you for a blast down Memory Lane. And thank you that you always show your restorations working at the end. Toys are MEANT to be played with!
