Your other frame with the 452679 serial number should have a letter prefix of either "S" or "AO." If it doesn't, then it may have grind marks where the original number was and a new number stamped. The serial number range is that of a Savage made 1928A1 Thompson and my guess is that the Full Auto markings on this one will be on two lines. Some guns, when rebuilt, had the original serial number removed from the frame and restamped to match the receiver they were being placed on. The S or AO prefix was usually not stamped when the frames were renumbered.
On your other frame when you say you lay it on it's left side and the grip facing towards you, do you mean the finger groove part of the grip facing toward the right? If that's the case, then the number isn't stamped correctly for an Auto-Ordnance made frame. If the grip frame is placed with the flat side down (the side that mates with the receiver) the AO prefaced serial number should read left to right starting at the rear of the wood grip and continuing toward the frame latch recess. I believe the Colt serial numbers are stamped this way also, but I don't have a reference at hand while I am typing this.
The Savage S prefaced numbers should start at the frame latch recess end of the frame and read left to right towards the rear of the wooden grip. I am doing this from memory so I apologize up front for any errors.

Thanks for the clarification, I thought that is what you meant.
Since the Full Auto is on one line and the number has no AO preceeding it, my guess is that someone took an aftermarket WWII frame, engraved a number on it and had it refinished. The aftermarket WWII frames had no serial number engraved on them.
The other frame is, I believe, a Savage made 1928A1 frame that was rebuilt during a government rebuild program during WWII and had the frame renumbered to match the receiver it was being placed on. The serial number range would be consistent with Savage made 1928A1 Thompsons and the Full Auto on two lines indicates Savage manufacture. The later rebuilt 1928A1 guns did not have the serial number ground off and mismatched frame and receiver numbers are common.
I hope this helps. When you are able to, post pictures.

It's your call, obviously, but I think I would go for an early A.O. made 1928A1 Thompson. The Full Auto markings on one line are consistent with the A.O. guns and that aspect is more visible than the serial number which will he hidden by the butt stock anyway.
On the other hand, if you wish to make it look like a Colt gun, the serial number range is correct, but the markings aren't. You might have more difficulty locating the knurled selector switches to make it look like a Colt gun, although PK can take the existing ones and make them look like the Colt type. Finding an early magazine catch release lever without the hole in the center is another matter.
I might opt for the early A.O. 1928A1, but it's up to you. Either one would be nice, I'm sure.

The hole in the mag catch can be welded and the checkering re-cut to make it look like a Colt mag catch.
