Hi Will,
I think that you just made a fairly significant point above and I wonder if you can provide a list of these crucks including location, builder, year of build, number of bays, use, etc.
From a building research point of view it is usually a matter of some academic speculation as to why and how a particular building style arose in the landscape and here we should be able to provide at least one (or more ?) definitive reason behind this apparent Bershire phenomenon. This would make for a good article.
On a minor point I think that you will find that the highest cruck concentration acolade probably belongs to Sheffield, Derbyshire, England (inc. imediate surroundings).
Regards
Ken Hume
