> Who has it for sale, and how widespread is its use?

Can I suggest a Google search for suppliers?

As to how widespread, I would have to take a wild guess: perhaps <5%.

I found this to be relevant to our discussions on the merits of pure subspecies (from buckfastbeekeerpersgroup.co.uk):

'As mentioned above, there are numerous Buckfast breeders, the majority of which are in Europe. These breeders continue the work started by Brother Adam. It is a big responsibility; the work done by Brother Adam cannot be repeated as some of the original material used is not now available in its former state, the reason being either through heavy hybridization or extinction.'

Best wishes
