What's this bracelet link?

Hi all. I won an auction for a couple of links for an Omega 1503 bracelet. The listing said they're genuine used links and only had one photo. It looked weird, but I didn't think much. Today I received them and they're no links for a 1503! Different finish, middle part is wider, different profile, and it's held on by screws.

Tried to take as many clear photos as possible. I'll be opening a case on eBay, but before that, I'd like to get some ideas. To me it seems like links taken from a fake bracelet on a fake Seamaster 300m.

Looks like a link for the 2018 model bracelet, not the old one you have. The new ones uses screws to keep the bar in like that. Can’t be sure of the proportions, though, but they are thicker, just like you show.

Thanks for the input. It indeed may be a link for the newer bracelets. Talked with the seller and I'll simply return it.
