I bought the five speed hub for a couple of quid a few weeks ago, if I remember the hub date is around 1990, it did not come with a sprocket or any of the other parts. Failing that I have a spare dynohub from 1967 as well as a spare 3 speed shifter. Lacing wheels has never been my strongpoint so while it may be less skillful I have seen ready built sets of wheels on ebay, some with a new three speed hub. Thanks for the advice everyone and for shedding some light on this bike
