Just down the road from where we hold our Humber Club meets is a little garage, here's a couple of photo's of car we saw at this garage a couple weeks ago.
I think the garage is called Pop's Place, it's next to The Half Moon Inn at Rushall, which is the village between Dickleburgh and Pullham. They mainly do Morris Minors, but do from time to time have little gems like these.

If you do go up there, makes sure you go to The Half Moon. It's lovely pub and serve Woodfords Wherry and some very nice grub.
