Can anyone tell me the make and type of this gearbox please? It's in a TT in the excellent Jedimar Museum in Santiago, Chile.
It resembles the Fuller and Moss gearboxes sold in the UK, but isn't exactly either.

Looks like perhaps a Universal ?

At first sight it looks quite possible, but I found another picture of the Universal here:

and that looks different. Similar, but different. Maybe an earlier or later version from the same company perhaps.
But thanks for the suggestion.

Here:

No through-bolts joining front and rear, and a different, rather vulnerable drain plug.

Chris

This is it, the Moore, has all the same features.

Another adv. this one is earlier, and shows complete unit, not a cut-away.


FordOwner April, 1918

Looks a lot like a Rocky Mt. Three Speed too. Dallas has my old unit, what do you think Dallas? Dave

The bottom is different than Rocky Mt. Rocky looks longer also. Its in rear building or I would post a photo.

Dan,
I think you have it. Moore it is.

Thank you.

I have now found other links which tell me that it gives 1:1 or .51:1 as an underdrive (as in this case). But it could be supplied as an OD, in which case the ratio was 1.667, so the OD version must have different gears.

See here:

Here is the rest of the TT:




Note the steering centering device. A rod from the wishbone ball joint to the centre of the axle, with coil springs around the track rod.
I like the 'shortened' gear shifter!
