Bernard, I do know where Brackley is, as we frequently visit the Brackley Antique Cellar, which I recommend for a Sunday afternoon browse - it even has an excellent little tea room!

It's only an hour or so from us - although admittedly we are situated somewhat to the North-West of London

However, I mentioned Basil because I understand he regularly comes down to London to collect glass for repair from various London dealers. I have heard specifically of some based at Alfie's who use his services and speak highly of his work.
