Hi Mark,
Great photos, wish I had gone now instead of working .
Now don't ask me about cars, not my line at at all barring the odd one, but I could tell you chapter and verse on the Austin fire engines or Bedford MW :-D
That Morris Z GPO van ..........they were in service when I was a kid and the Royal Mail ones, nice to see he has all the bits and pieces in the back, wonderful stuff.
I see CW was a CPO then....so much for his smokescreen :-D
