Re:

Well i have checked the ratios and as the lower four cogs are fixed it is the top three that have been messed with .
so its a 28 to 18 then a 16 a plain spacer ring then a 14 and finally a 12 with built in spacer
Thanks to everyone for there input , such a shame as its a lovely light cassette :roll:

To me I think it's just missing the 11t cog. Could be wrong as I can't quite remember the ratios they came in but most I've had started with 11t. If that's the case, you'll just need an 11t cog and a lock ring compatible with it as the 12t lock ring will be too big.

Re: Re:

Add to this the vast number of people using DX & XT 7 speed thumbies 'with the hidden click' (which really isn't hidden as we all know it's there) with no issue on a 8 speed setup (myself included) again would confirm the spacing is close enough otherwise it wouldn't work and speaking personally I have no shifting issues.

8s w. 7s shifters can be made to work if everything's clean, no slop (wear) in the derailleur parallelogram + cage bushings, and set up properly. It is nowhere near perfect. Maybe you cant't notice, but I notice the shifting falls off at the top and/or bottom of the cassette if the upper pulley is dirty or there's wear in the bushings.
