What size / part no. Metal wheels for oo Mk3 HST coaches

[flockandroll]

Hi, getting side-tracked by my son's HST... 

He has a Lima Mk3 coach missing a bogie, so while ordering other stuff from Peter's Spares got a pair of Hornby Mk3 bogies, no wheels or hooks, but I have wheels...

But turns out 14.1mm coach wheels are rather steam age... 

Do I need Hornby R8096, variously described as 12.6 or 12.mm, or do I need 12mm as others say? I'm trying to get a Lima coach to run on Hornby bogies in a Hornby HST. 

Oh, and some etched brake discs look very nice to add on, but probably over kill.

Thank you for any help or suggestions, 

Flocky

Yes, 12mm wheels for Mk. 2 and 3 coaches.

Looking at the real thing:

wheel diameter new 914mm,

after last turning 842mm,

scrapping 836mm. 

At 1:76 that's approx 12.0, 11.1 and 11.0mm.

Hornby R9086 are a bit bigger than 12mm and described as "mostly for wagons".  However I want to match to a Hornby train, so I guess that's the way to go?
