Take a look here: http://www.motos-anglaises.com/ A French site with lots of bike catalogues. Go to Motos, then on the right catalogues, then look for BSA then 1959 USA Anglais and it's all there.
Thanks for the heads up on this site, one I have not come across before.
Just finished downloading them and catalogueing them.
Bad news is a lot of them are named incorrectly as MR Motos-anglaises oviously did not know that BSA model Years start in August.
Also he has the disgusting habit of taking images from elsewhere, and in particular OldBrits then adding his own watermark to them passing them off as his work,,,, Big fail.
Why people on the web have to carry on in such a decieptful way is beyond me, like as if no one can google BSA Catalogues.
Sheldons Emu has always been the best general Bike site for old iron and at least he only watermarks what he has actually scanned himself.
So chck the publication dates before you get too excited.
