1) the frame may have been shipped as a replacement part. I have a very rare SAA from the 1880's that does not have a serial number. One of 25 known however it is well known among collectors that Colt shipped 200 SAA frames to the US Gov. as replacement parts.
2) Some guns known as lunch box specials were, uh "borrowed" from the factory, assembled by employees prior to all markings being applied and smuggled out in their lunch boxes. There are many known 1911a1's that are Clearly Colts with no markings
3) Factory errors. Even Colt made shipping mistakes
4) Colt is known to have used virtually every part ever made (they were cheap bastards!) and at times when guns were needed took stuff from the parts bins or overrun parts that were stored for years to assemble and ship guns.
5) And quite honestly the most common issue is that the gun was refinished and the serial number has been removed.
Regarding legality no serial number guns are 100% legal if made without the serial number. However its heavily frowned upon by the BATF to remove a serial number from a gun. Given the photos you posted I don't believe your gun has been refinished, but closer examination would be required to make a final call.
