Bernhard, you forgot to mention the BA thread. Used in various electrical parts, and in some odd places.Even metric threads was used (rarely). After around -68, UN threads became more common.Norton used cycle threads (CEI, BSC) even in places where good engineering practice would be BSW. Vincent preferred BSW and BSF.
