Aah! Thanks Richard, I've had a closer look now (I'd only quickly skimmed the SD folder). I took the file numbers to be the same as the sheet references on the First Series sets - don't know why - especially as they are derived from 1:50k data! Just as a matter of interest, I'm viewing the files in Openoffice. The drawing app. provides a quick and easy way to view the files graphically.

I've by no means checked every one on my download, but a look at quite a few squares show that I have all the ones I expcet to have for those squares. _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
