I have a mid fifties Claud Butler Jubilee model club bike. All the equipment except cables, tires and frame paint, is absolutely original as my late friend purchased it in 1956. My question is the steel cottered Williams 5 pin chainwheel is not stamped as a Williams even though it looks identical. It is stamped as UTILITY Made in England. Could this be left over equipment from WW2? Maybe the British list members may have the answer. Robert Murray Snow shoeing in Toronto
