The Gault foldable boat, I have one of these extremely rare boats and still in its bag.
The Gault foldable boat was patented by Robert Gault of 12 Ranmoor Cliffe Rd, Sheffield, England S10 3HB. The application was filed on the 31st March 1980 in the USA and accepted on the 7th December 1982. I am not sure where it was made or who actually designed it, but I plan to find out?
