Late production RIA used by USMC?

[usmartial1950]

I've come across a late production (344541) RIA receiver, 1-31 SA BBL '03, with many of the traits usually associated with Marine re-builds. But before plunking down any cash, I was wondering if anyone could enlighten me regarding the possibility that this RIA receiver could actually have been used by the USMC during WWII. Thanks in advance for any insight anyone might have.

what USMC traits does it have?

I mean it sounds pretty decent so far. One thing you might look for with a 31 dated barrel, especially if it has a hatcher hole is a numbered front sight. Like a .40 or something close to that.
