He knows guitars - he's a semi-pro folk musician and has been since the 60s. I gather from his description that it is twisted - and I thought he conveyed the body was distorted as well as the neck. I think the strings were longer than standard scale length (like the "D" Ovations) and also thicker than standard heavies - and its a twelve. Location - North Kent, England (about 40 miles from London). Do you know if there was a thing officially called a "Street 12"?
