Every town must have one - a shop that defies classification. This is the window of Cambridge Leather Bags. I bet if you asked anyone in town where this shop was they wouldn't have the faintest. But it's been in the same place - Sussex Street - for as long as I can remember. And I've never seen anyone go in or come out. How on earth does it survive? It sells leather stuff for sure but also travel clocks, pocket watches, shaving brushes and cut-throat razors... exactly - that's what I mean! Long may it stay.
