This should have been material for the This made me laugh-thread. I fear it might not be, so I'll post it here. From my 1995-brochure.
I love these old nostalgic bits from the good old days. I remember, when I worked for a Triumph dealer in the '60's, we said BSA stood for "Bastard Stopped Again." A few years later when the two combined in the US in the early '70's and we had to start selling them, BSA now stood for "Best Sonofabitch Around!"
