Quite possible, hadn't viewed the '63 Fall and Winter catalog yet. But the stays look the same to me for 63-65? The 65 Fall and Winter catalog shows it with a different chainguard and maybe the stays too, the item number changed also. I am not familiar with them enough to know the nuances.1963 maybe? I think the fender braces changed on the later 60's models.
