Stevens 200 actions?

I am thinking about picking up a good used Stevens 200 action in .223 for a project but was wondering if there were different generations of these actions? Are they all the same as far as where the bolt release is , action bolt spacing, and the feeding system? Is one any more desirable than the other?

Thanks

Stevens 200 is a Stevens 200. They are very straight forward unlike the Savage version. Bolt release is on top. Center feed spacing 4.4" Blind magazine.

The Stevens were both staggered feed and center feed.
4.25 4.40

Yep...
