Early Babbitt HR Link

How can you tell if a HR Link is an early Babbitt or not? I know they have more baffle and a higher floor. Do they all have a slimmer beak? I had one years ago that I got rid of because it was too open, and I don't think it had the slim beak. It was real nice piece.

I'm asking because I recently got one in a trade and want to make sure I got what I was supposed to get. The beak is not the slim beak of the Slants, but the baffle/floor are like the one I had before. The rails are really thin.

Did they make early Babbitt's without the slim beak?

Thanks!
