Shaun,
I don't know how you do it, pulling these amazing rabbits out of the hat! Such a wealth of information, and fascinating, too. The sale of those Bertram Mills items particularly interesting, amongst many other factual stuff.
Very many thanks, as usual,
Keith
P.S. Trifling matter, but I imagine George Futvoye Francis' death date was perhaps 1929 rather than 1829...
