Good Point BAR
While searching for information about the OP's gun,
I've looked through a number of Colt letter images on the net.
See that many during War time production don't have a 'Manufactured date on it'
Then when looking at post War letters, many DO Show a production date.
IDK, Will assume as seen that some letters have made on dates, some don't.
And as I posted above, sometimes the Colt letter calls the finish Blued, when it is actually Parked.
Either way would love to see this one.
VR,
