A 1911 is W.W.I. A 1911A1 is W.W. II. There were commercial Colts sold then too.
These guys list S/N's by year of manufacture. No Inspector RWTR though.

The "in like new condition" would be ringing alarm bells for me. Too good to be over 100 years old. SN 1514, if that is the S/N, indicates 1912 manufacture for the USN with a total of 500 pistols made that year. Mind you, it might be an inventory number from some civilian organization too. Either way, $2200 isn't ugly, I've seen GI issue .45's at more than that, but I'd want more info on the thing's history.
Spelling and grammar count!
