From a previous post by Gary E..."About 18600 '67's (all models), about 11000 '68's (all models)."
Here's a quote from the "Shooting Star" book which might explain some of the late shipping dates in 1968, as well as the lower numbers sold. Providing it's true of course, I'll try to find confirmation in the Hopwood book and elsewhere.
-“The first warning signs of an imminent collapse came in 1968, when a combination of labour troubles and missed production deadlines by a host of subcontractors caused BSA and Triumph to ship motorcycles to America late in the spring, which meant the firm missed much of the “selling season,” as the British always called it. This is likely why the new triples weren’t seen in American showrooms until June that year. The company was forced to buy back several thousand machines, mostly twins, and dump them on European markets at a loss.” (Aamidor, 2009, 115/116)
Following up on 11/18 2011, here's a relevant quote from what I consider to be a trustworthy source.
In reference to the 1968 season... -“Large stocks of BSA motorcycles, which had missed the US selling season, which generated 90% plus of the division’s annual income and profits, were brought back from America and had to be sold off at a substantial loss. This was due to late design changes delaying completion of the urgently required motorcycles” (Heaton, 2007, 128 )
This quote from Joe Heaton's thesis references Hopwood, 1981, 228 and 240.
