The bicycle was bought for me by my father & grandfather to go on a cycling holiday to France in 1963.  I remember that the bike, which was bought at Young’s on Lee High Road, Lewisham, had been reduced from about £30 to £21 having been returned soon after purchase. It was new, but briefly used. It certainly came with Weinmann 27 ¼ inch alloy rims (which I wrote off going into a drain gulley & replaced with steel rims thereafter) & Campagnolo gears with only 1 chain wheel & 5 gears. It always had Milremo centre-pull brakes with Mafac cable yokes.  It had red mudguards to go with the red “Youngs” transfers, & it was always a metallic light green.   Now undergoing restoration
