I didn't take pics, as I was in a mad hurry to get it together to get to the range. But I did stack the two on top of each other just for a quick comparison and they had slightly different profiles. And it did look like the 452 extractor was slightly curved/angled under the hook, the 457 looked straight. The body was slightly different as well.
Not at all scientific, but they weren't exactly the same.
I've put a few hundred more rounds downrange with the 457, perfect extraction/ejection. That older extractor was the solution for mine.
