I had the recent opportunity to need the 1960 Matchless Spares book, available free from the AJS/Matchless Owners Club Archives (http://archives.jampot.dk/).
Since they were an optical scan, I took some time using my OCR tools and made them searchable. They are available here. If anyone from the club would like to upload them to the archives they are more than welcome to. I only ask that they be freely distributed.
You can download it here:
