There are some other clues, like if you have adjustor plates on top of your rudder castings, all Aluminum mast or composite tip, aluminum finish rails or black anonodized rails/mast, etc. but for the most part there have been so few changes, and none of them major, that it is hard to tell and doesn't seem to matter much if it is solid and well maintained.
Also, so many folks have retrofited newer parts on older boats that even the clues are misleading at times.
Enjoy it! Post a picture and we can tell roughly the era asuming it hasn't been modified much.
Welcome to the Forum! There is a ton of info here.
