Thanks Kevin,
and today I saw a photo of the Riley Two Point Six - which had the original version of the " C " series the 2639 cc with the restricted manifold that made the 100 Six so wheezy.

That Wolseley engine is interesting, didn't they make them quite small as well, around 1500 cc for some of their smaller cars ?
