Whilst i don't know the area as well as most on here, I do have two glass plate slides in my collection showing Watt's Place, one each from either end. Interestingly, the image posted by Smiffy is a reduced version of one, which I include in its full format, with the second image looking down from the other end. Interestingly again, the pics i have are generally thought to be from the first half of the 1950's, whilst Smiffy suggests the first pic could be as early as the 1940's. Is there anything in each image that could clarify this?
