3TA/5TA Gears

I have found a 3TA or 5TA bottom half in the back of my garage but cannot identify the gear cluster fitted in it.

I believe it is a close ratio box but the strange part is the sleeve gear and matching pinnion on the lay shaft, they have 26 and 18 teeth which is different to my other similar Triumph boxes where they only have 22 teeth on the sleeve gear. It also has a large 20 tooth gearbox sprocket which leads me to believe it was originally destined for the track.

The profile of the teeth on these two gears is different to the other gears and I believe they are meant as a very high top gear but where did they come from or who made them and what effect would it have on a good condition 500cc top end.

Any info would be appreciated, cheers

Any chance you can give me a clue as to where in the country you live, I'm in Surrey and may be interested in some if not all the parts as long as the price is reasonable, you can P.M. through this site.

just put the 500 related stuff pictures on here and a price and I'll let you know, and what county your in as distance will have a bearing on purchase.

Am just as dubious as you about giving personal info out which is why I only need county.
