Awesome photography @Mr Smith ...it does look to have been polished around the outer coined edge at some point: just not 100% evenly and the "sunburst" looking machine finish can be seen it a few spots.On closer inspection for future reference
The machining and brushing can help I'D gen bezel from aftermarket bezel. Even though TC done a great job brushing and machining his bezel assembly especially the PA#2, They are brush lines you can see on gen with a loop!

This can be tricky because gen used bezel gets serviced polished over the years and can look rep as hell after being polished to death.
I'm guessing the condition of the retainer is the result of someone having one helluva time trying to get a bezel ring to fit it ?
I know at one time the retainers that came with the purchase of a ST3035 case were know to fit gen bezel rings: I've done it a time or 2 myself.
WM9 V3, some Seans and yes, even some TC retainers have been able to accept gen bezel rings...so it's really hard to say "exactly" which of these it is...if any of them at all.
