Please help identify this very early Sub bezel

[watchthisone2]

Hi, Any one know the what model the first bezel comes from?
I purchased the second thicker one to go on a 5508, which seems to be correct, but the supplier sent a wrong insert. I made a complaint and he sent me a new set that included a vintage insert. Problem is that he insert from the first picture does not fit the 5508 bezel. It is slightly too small and has a different profile as it seems to be shallower. The last picture shows the two together. If the thinner bezel and insert are genuine, I will sell them to fund my search for the correct insert. Hope this makes sense! Any help appreciated, thanks.
