Thanks for your efforts Steve. The hatch on that A24 is very similar apart from, as you say, lack of locking bolt. Was this type of cupola hatch used on other tanks?
There was almost certainly only one tank in this location. I'm also fairly certain it wasn't a Churchill. My dad's clearest memory (bearing in mind he was only about 4 or 5 years old at the time lol) is of a really short stubby gun barrel.
That area of the moors seems to have been used by the regular army, rather than home guard. There was quite a lot of Universal Carrier activity, track marks still evident when they burnt the heather off about 20 years later! Have also found remains of 2 inch mortars, spent .303 rounds etc.
Amusingly, at end of war a soldier told him and his sister they could have the tank, so they headed off home to return with a very tired horse, with a view to pulling it off the moor. I guess at that point someone must've pointed out the futility of trying haha
Just looked at pics again. The hatch in that photo looks fairly straight, whereas mine has a definite angle to it. Hmmm....
