Help on ID a 1911...

Would like to tap the expertise and opinions of those 1911 gurus out there if I may. I picked this up on the cheap, and don't know what to do with it....it functions fine, and I know some parts aren't proper. Real curious about the SN, with the xx suffix, and the really awkward US Property stampings. So, do I pretty it up, leave it alone, sell as a package, or part it out? Many thanks in advance, and happy Labor Day!
......apologies for the sorry photos

Looks like a rebuild with a buffed slide. I believe a Colt but I'm no expert on these. ;)

To save repeating myself.

Help on ID a 1911...please

It is a mess. The frame may be an Argentine and hopefully with an original serial number. The added markings apparently are a mix of fantasy and attempted fake US military. The barrel is a high standard. Slide is a mess and could be M1911 but hard to tell. Hope you paid very little for that.
