Determine if Engine has been Rebuilt

Good Morning,

I'm trying to figure out if the engine in my 120 has ever been rebuilt.

The only thing I have to go on are the following details.
1. The odometer was showing just under 17000 miles when I got the car; has almost 21000 on it now, 2 years later
I know that the odometer can roll over, and this is no guarantee of any actual mileage
2. The gaskets seams on the engine all appear to have the same level of patina
3. I am curious if anyone knows if Packard used Pal Nuts in engine production, specifically on 19th series 282 connecting rod bolts, as lock nuts on top of regular nuts. See attached picture.

I did turn up Patent Number 1899715, which was issued in 1933.

Thanks,
Chad
