Here's an example of a '69 US spec. Lightning: http://www.acay.com.au/~shanep/catalogs/1969/69_10.JPG
The tank badge 'looks' as if it has a red background, but I'm not sure it actually does (or would have done?).
The sidecover decal shown is different.
I know Triumphs of that period could differ in specification between East coast and West coast models, and that may have also applied to BSA models as well?
You may need to ask others with more specific US model BSA knowledge to get an accurate answer about certain details?
