If you can't get one, I am sure they are still available at bike shows here. I'm going to the big show at Stafford in a few days, so I could get one to you.
Wow what a lucky guy! It looks like your bike is in pretty good condition for its age. I am working on getting my dads 1964 CA95 150cc running, they look very similar. On this web page (http://www.vjmc.org/techtips/carbondating.htm) it seems that your bike is a late 60's model, as 7 digit #'s didn't start until 1965.
I see the tank difference, as mentioned above.... mine is much more "bottom heavy".
