Originally the toy Museum and the Gift shop you refer to was a lovely old cottage. The Toy Museum is still there and the Gift Shop was demolished. At the back of the Gift Shop was part of the old building.
There is now a fudge Shop where the Gift Shop was and also a vacant shop next door
The rest of the building has also been replaced I believe into flats
So you were quite correct but afraid I cannot tell you anything about the black cat!
