This flyer appears to be a very early version from the Viking Londonderry period. There is a reference that the bicycles are designed by the well-respected Liverpool bespoke frame builder Harry Quinn. However, the flyer does not appear to be complete. It is included here for historical reference. The bicycle models shown are not identified but are clearly high-quality lightweight specification steel frame bicycles.
