Oh beauty! Was my first ever MTB, bought from Williams cycles, Cheltenham.
If it wasn't so small I'd be after it like a ferret. I did actually buy one recently, advertised as a 21" and it was simply tiny in reach. I'm normally 18"-19" , I think my first Dawes was more like a 22", there was definitely a good two inches gap between top and down tube where they met at the headtube .
Bah.
