Thanks muchly for the post, Aggie; it has produce many mental images (and I do mean "mental"!).

Please also forward my regards on to Les along with my best wishes for his continued survival. I haven't forgotton that pint (or several) I owe him for his articles on split-grade printing (without which I'd be even more useless than I currently am!) and our proposed meet up in the Lakes this Winter.

All the best

Frank
