ETA: I don't think the copper plating has any relationship to early or late, I think it was intended to help with either wear or friction. I've seen NOS worms and NOS sectors what have the copper plating on them.

Thanks for the photos, a picture is worth a thousand words. Those are great photos. A few years ago when I rebuilt my first gearbox it had early parts and I discarded them. I have regretted that ever since. Thanks again.
