Strange gearbox

[joeythescooterboy]

Just stripped what I thought was an early P2 lump only to find that it's a Rally 200 motor with Ducati stator.
had a look at the gearbox and I'm goosed as to what it's from......

Xmas tree= 67 primary, 27, 22, 17, 13.

Loose gears = 42, 48, 52, 57.

Ratios are 1st = 13.32 - 1
2nd = 9.27 - 1
3rd = 6.62 - 1
and 4th = 4.72 - 1

none of these ratios match anything I've found so far although they're as near as damnit to P2 box.
Last point is that the loose gears are on an EFL layshaft with flat cruciform so it's obviously a bitsa but it seems to have worked ok in the past.
Someone help me out and tell me what gearbox it is.

One more thing..... did UK Rally's have autolube??

some uk Rally 200"s had autolube, but not many, they are very rare. some 150 supers had it as well , also very rare. what about spanish DS 200? they throw up wierd anomolies from time to time i.e. odd ignition set ups, wierd forks, funny seats, maybees funny gearing and autolube?

I've checked out the engine prefix VSE 1M so it's definately a Rally motor, it's mostly the gearbox that's throwing me.
I can't find the primarys or lose gears listed anywhere.

Isn't the Cosa 200 gearbox an odd one?

Sorry should have said......................................................
I've found out that it's a 150 super gearbox, why they'd change it I don't know although the ratios are not that far different. It's higher in 1st, 2nd and 3rd and then lower in 4th so maybe that's why?
