Carol,

That's great - many thanks.
I'm merging all my snippets, and trying to resolve (and write-up/explain) differences.
However, I'm not adept at all this, and identifying differences (for example with CKR's linkages) and finding the history and reasons for the differences is proving tricky as I'm coming to this rather late, and have no feel for the provenance issues involved. Any tips anyone has would be gratefully received.

However, I'm wondering off the Radcliffe thread with this, so will stop.

Kind regards - Bernard Diaz
