There's probably a complete write up on this website somewhere but I'm new so you'll have to forgive my ignorance.
Thanks, Paul.

The Mk.1 and Mk.2 Coopers had:
Chrome trim strips around the door window apertures
A remote gear change consisting of a long aluminium alloy casting containing the gear shift linkage.
Twin 1.25" SU carbs on an alloy inlet manifold
A 3-into-1 tubular exhaust manifold (a lot will now have an LCB exhaust manifold)
Disc brakes, 7" on the 987 and 998 and 7.5" on all 'S' models
A 100 mph speedo on the 997 and 998, a 120 mph on the Mk.1 'S' and a 130 mph on the later 'S'. Other Minis had a 90 mph speedo.
All Cooper models had a boot board covering the spare wheel in the boot mounted on brackets. No other Minis had this.
After about March 1966 all 'S' models had twin 5.5 gallon fuel tanks
After about April 1966 all 'S' models had Hardy-Spicer drive shaft couplings
All 'S' models had 10 head studs and one head bolt instead of just 9 head studs on the 850, 997 & 998.
All 'S' models had rear drums with a built-in spacer.
The 'S' steel wheels had holes around the web of the rim
All Coopers, 997, 998 and 'S' models had short chrome interior door handles, unlike the 850 which had door cable pulls.
The Mk.1 Cooper and 'S' had grey seat and interior trim with a coloured fleck effect. Most Mk.2 Coopers had black trim.
A Cooper usually has a different coloured roof, although single colour cars were made.
The Cooper 'S' has a brake servo as standard.
The Mk.1 Cooper and 'S' have black leather-cloth trim on the lower and upper dash rails and right up the A-post to the head-lining.
Those are the main visible differences. I could go on to explain how to tell a genuine Cooper 'S' engine from a non-'S' 1275 unit and will do so if you wish.
I hope this helps

Thanks for the infoHere we go, and I'll probably miss something.

Yes I'd be interested to know how to tell the genuine engine apart.
Cheers, Paul.

1275 's' engines have chest covers at the back like small bores, but 'normal' 1275s dont i think. probably some other stuff concerning an extra head stud I think but thats the easiest way.

It's less easy to check on a 998 Cooper, but the differences I listed are a good start.
