Hill's Rubber, Reading.
Brilliant shop. Basically unchanged since 1888, when it opened. An old man in a brown warehouse coat serves you from behind a glass and mahogany counter. When you make a purchase, they hand write the receipt on a wooden till with a drawer that rings a bell when you open it.
The last time I went in there looking for a hose for my boat, the fella asked me what diameter I wanted. I said it was 32mm. He gave me a hard stare and said "Inch and a quarter, son...".
Saying that, someone told me they moved.
