I can only think of 5 different types....
1. Thin, Smaller T-Handle, Tapered, Chrome 64 1/2 Only.
2. Typical T-Handle (Most Seen), Tapered, Chrome '65-'68 (The one that is most heavily reproed.)
3. Slanted T-Handle, Thin, Vinyl Wrapped '67-'68 (Keyed to interior color) - Possibly '67 Only?
4. Larger T-Handle, Slightly Tapered, Thick arms, Chrome, Mid- '68-'70
5. Shelby T-Handle, Large Round Wood Ends, Embossed Cobra in wood '68-'70.
I can't think of any others...
From Your PDF file, The one on the left looks like a Typical #2, The one on the right looks like #4.
