Default 1911 or 1911A1 - Arsenal Rebuild?

I received a very nice "Field Grade" pistol from CMP last week. I have a question regarding the pistol, the serial number places the date of manufacture as 1918, but it is marked on the receiver as a "1911A1". Is it possible that it was originally built a WW1 era "1911" and was rebuilt between the wars as a "1911A1"? My limited research shows it has all the attributes of a 1911A1 (exception of an unusual hammer). Any help would be appreciated!

Frame - Colt Serial #457804
Frame Markings - Rightside - "No 457804" & "M1911A1"
Leftside - "UNITED STATES PROPERTY" - Springfield Inspection Mark "Eagle Head" over "S2" & the number "25" on the trigger guard in front of the magazine release
Slide - Remington Rand ("P" proof mark)
Slide Markings - ("P" proof between ejection port and rear sight)

From the pictures it looks like the A1 could have been added and the finger cuts were done later also, stamping and cuts done very well. By number it’s definitely a 1911 but number and cuts very well can be factory, either way you probably have one of a kind very nice pistol.

Some arsenal rebuilds of 1911's added the relief cuts and many more were marked M1911A1.

I have a blued 1916 Mfg 1911 pistol with finger cuts in the frame , no rework stamps on the frame. I purchased the pistol about 20 years ago. I need to figure out how to post a pic of it. It is interesting that the USMC reblued their pistols.
