I've just read through the whole thread and it's reminded me how much I still like the very early cars, how 'right' they looked and their little peculiarities such as end-of-dash map/courtesy lights, troublesome exhaust etc.. The fact that it has (presumably the original) non-suffix regn. number makes it look very 'period' and takes me back many decades go my first car, also a pre-suffix registration A-suffix chassis (regd June '64). Unfortunately, the only thing remaining is the regn. no. which I still have.
As a comment, reference your post #242 re 'seat belt hooks', mine was fitted with them from new (they were plastic and from memory were either creamy coloured or just opaque plastic).
