Reg Harris was a famous British track racer in the late 40's and early 50's. He won 2 silvers in the 1948 olympics and 4 world sprint championships. I remember when surprisingly he won the British sprint championship in 1974 at the age of 54! He had a friendship and connection to the Manchester frame builder Johnny Berry. They belonged to the same cycling club. I shipped home to the US a lot of Johnny's equipment after Johnny died in 74.
According to Wikipedia, "he started a 'Reg Harris' bicycle manufacturing business in Macclesfield which lasted three years before folding."..That was in the late 50's. That was new information to me. I vaguely remember Johnny Berry telling him the only time I met him in 74 that he made a frame or two for Reg Harris. He was sponsored by several bicycle companies throughout his career.
The position of the down tube decals makes me think it is an amateur respray.
