Hi P!mp - it's a late 60s(?) Claud Butler steel track frame (I assume Reynolds 531 by the feel but no markers) with Nervex lugs - original parts include Normandy hubs, Stronglight cranks/chainwheel and Cinelli Pista bars (may be later addition). Originally had Champion rims for tubs but changed these out for the ubiquitious Mavic Open Pros for clinchers.
Riding 48 X 16 (with flipflop 15) just about do-able for me as I live at the top of Crouch Hill.
Frame is a bit neglected - getting more and more Hammerite on it to cover up rust - maybe one day a proper respray is in order.
Also frame is a bit on the big side to what I prefer but it's a great ride!
A bit too big for you? You should sell it to me then;-)
