1967 Raleigh Winkie We have obtained a trike that my husband used to ride as a youngster in England, and then here in the States. It had Raleigh written all over it, and the model name appears to be "Winkie". Not sure of the date of manufacture and cannot find the serial number. Have had no luck in finding anything on the rear hub. We are interested in restoring this tricycle for our son, but would like to obtain any information we can before doing so. Can you help with a useful website, or perhaps a book? Can you tell me where we might find the serial number? Thanks
