"Buckler Boats" / "
Buckler Boat Company" was the name of the company responsible for the Buckler Ketch. I believe they are no longer in business, but they seem to have had several addresses, including: 12 Portland St, Southampton, S09 4LA, and 1 Bryanston Avenue, Guildford, Surrey, UK, so if you live near either of those please have a look in and ask around!
I believe Bill Mayo is (was?) the designer of the Buckler Ketch, and you may be interested to know that
http://www.blaxtonboats.co.uk/ still produce the Bill Mayo re-designed Islander 17.
Buckler also did a vessel called the "Bowie"... I don't have any information about that either!
