Hi Edward,

Had a look at your bikes on Wooljersey...as well as the Elswick Hopper, which is certainly a interesting machine....... my eye was drawn to your lovely 1954 Bianchi Campione Del Mondo.......with those mudgaurds [fenders].......absolutely stunning!

Nice collection.

Cheers...Kevin Sayles
