Traction Engine Gears

hardy747 · 24-05-2008

Hi there.
I'm looking for any info regarding a set of traction engine gears that I've inherited. They are all in 10DP but I'm not sure of either the scale or the model that they are off. Guessing that they are about 20 yrs old.
Starting with the two speed drive there is a 17T and a 27T pinion, 1/2 face, both with boss and slider fork groove. These mate with a double gear of 69/79T.
The diff cage carries a 95T gear 3/4 face and this mates with a 25T pinion of same face width. One of the two bevel gears registers in the hub of the diff cage set, which is designed as a 2 bevel pinion set up. Also featured on this assembly is a flanged drum, the purpose of which I'm not sure. Could be either a winding drum or road wheel brake.
I've looked at old ME's and can't see it being either Minnie or John Hainings Light Compound Tractor nor does the gearing match a Thetford Town that I've looked at.
I've added some photos of the parts to my gallery on this site (see left)
Anybody recognise these bits?

I don't know what engine those gears are off, but by the size of the gear face width it looks like a 2" or 3" scale engine.
If the flanged drum has a very deep flange then it is a winding drum, if it has a shallow flange more like a groove then it is a brake drum.
Also most engines had a three pinion set up on the diff, so that might help in tracking the model down.

Thanks Mike for that. The diff case/final gear is about 9.75" and has the deep groove for a winding drum. The 69/79 gear also has a smaller groove which I see as the brake. What model is it off. Reeves cant help!
