Norton Atlas valves

I have a box of new & old valves but none of them are in boxes. I know that AE used to make valves for Nortons and went looking to see if I could find the numbers. AE used to put their numbers on the stem and I am hoping someone might have an old AE parts book with the numbers in it? Need the numbers for G15/N15 750's. AE doesn't list Nortons anymore.

Thanks in advance for any help you can give me.

Found the numbers using RGM's website.
