Parts books essential but they do not cover mid season changes ammendments and corrections which happened after the book was printed. These updates came on parts service bulletins, many of which can be found on the Club website.
The original BSA supplied parts books used a fine print , much clearer than many of the copies offered for sale today.
The W C Haycraft Book of the BSA Twins is a care and maintenance manual, with some illustrations, my copy indicates it was first published in 1960, second edition in 1963 with several reprints and minor ammendments in 1969. The later copies are not securely bound and often loose pages.
The other contemporary book was "BSA Twin Motor Cycles" by D W Munro. Simiar size to Haycraft book. Some developement history some maintenance. Author was the BSA factory technical manager.
