previous quote from Anne...................."It might be worth seeing if someone (Paul, perhaps, on his next visit?) could check that RD number and see who the registrant was, as that might give us some useful information too".
I was at Kew this morning - but had left the house a little before this was posted, and obviously had forgotten the matter from the original August posting.

Will have to wait for the next visit. Does anyone else currently visit TNA?
thanks to Lustrousstone for linking the pix etc. - wish I was that clever.
