BLACK, 1954 AUSTIN A40 SALOON
Well its not exactly black anymore! but I did think Somerset when I first saw it. From the ever reliable Wiki It was produced between 1952 an 1954 and it does look similar in style to this example of the breed in a nice beige.... nah thinking again its mushroom or magnolia isn't it
Jim's reference to other "County" variants inspired me to do a list from wiki of the "A" type vehicles made by Austin. They never quite got round to an Austin A1 Northumberland.
