What are we looking at? Is this a chain driven rear axle or some kind of gearbox?


Both. Each chain and sprocket set provides a different ratio, and obviously the axle is driven by only one chain set at a time.

Yes, and Yes.

Nash and Godfrey hated cogs,
Built a car with chains and dogs.
And it works, but would it if
They had built it with a diff?

Or, none! Here we see the Norris with just bottom and top gears, the chains having departed, several laps back, onto the track surface!

Julian Grimwade still managed a podium finish at Cadwell Park- although The Mountain was a bit of a nail-bighter for him each lap!

Thanks for the input on the Frazer-Nash Norris.

I love those old machines and sometimes I see some technical solution I don't understand on the spot. When I do my homework then and I get it, it's either the 'cartoonlike lightbulp over the head' moment or the famouse ' :eek: What the hell were they thinking? :eek: '.
