BCE crown guards versions ..?

[Sloth]

Have been looking through old posts for BCE pictures, and browsed for gen pictures- and I am confused...

There´s been a lot of discussion on the different versions V1, "original" V2, "new" V2, V3, V4 - identifying some differences. What I can not find anything about is the shape of the crown guards, and other case differences.

I have two different BCE cases. One is the "original" V2, and the other described to be a V2 (and because they ARE different, I am calling it "new" V2). The CGs are different (as well as some other things). On the original V2 they are thinner than on the new one. When looking at gen pictures- I seem to find both versions there as well. Is this a difference in production years? Anyone got insight on this? I see differences in some of the BCE pics here as well.

Anyone?

Thin CGs = "original" V2

Thick CGs = "new" V2

Sorry for the bad pics- but I guess that it´s better than no pics

I only have the 2 BCEs and one is a black bird so i never noticed the difference before, and you say you see the same in Gens?

The thick CGs seem to be more common, at least from the online pictures I can find. It might seem like the first BCEs came with the thin ones (similar to older Chronomats?), and then changed.
