An old friend of mine has a 'pre-select' gearbox from a 1935 / 36 Riley 9 for Sale. The gearbox looks a bit rough and dirty from being in his shed for many years and, although in working condition, it would obviously require a bit of maintenance. He is asking £350 for it. The gearbox is located here in Aberdeen and due to its weight ( about 30 -32 kg ) it would mean any interested buyer would need to collect it. Postage costs would be considerable I should think.
If you would like some more information then pse call me on Aberdeen 01224-861636 and I'll be happy to help but I must confess that I am not an expert in gearboxes .... Riley or otherwise! I would however be able to pass anyone interested on to the owner.
