Greenwell advertised gratings recently but I find that there website
is not running at the moment [ www.greenwell.co.uk]. You may know
someone who has their latest leaflet. I think they were offering 900
lines/mm strips @£7-99.

You have got their name slightly wrong! It is actually:

URL:http://www.greenweld.co.uk/

Sorry! Thanks Graham. I did mistakenly type in Greenwell and got just a
title page for a site which appeared to be under construction; hence the
confusion.
