Looks like you have a 1942 Colt - take off the firing pin stop plate and check the if the serial number there matches the slide. If it does the slide is original to the pistol.
Close up pictures of barrel marking will help to determine if the barrel is original.
The faded patent markings could indicate that the slide was refinished if the pistol is all original (matched slide / frame) it could be worth $1300 - $1500. If the slide was refinished and it doesn't match the frame $1000 - $1100.
Reid134: There is a rule put in place by the US government that flatly prohibits the importation of US military firearms once they have left the country. Since USGI pistols were actually made in the US and used by US forces, they have a much greater value to US collectors. I could have gotten twice as much for my gun in the US (in US dollars to boot) but was not allowed to sell there. Canadian forces carried Brownings. Canadian collectors don't pay as much. I tried to find a loophole but it doesn't exist.
This law is due to the fact that all the 9/11 terrorists were Canadian and used WWII Colt .45acp's![]()
And don't feel too bad about the mis-match slide on the numbers. As stated it is quite common.
When I did a 'resto' on my 1942 mfg "WB" inspected Colt frame the period slide I had for it had some after marked hi-vi sites installed on it. And the serial number stamped under the firing pin stop made it a 1941 mfg slide. [Top slide in pic]
I did find another period slide for it, with correct GI sites, but with no number stamped under the firing pin stop. [Bottom slide in pic]

Beautiful restoration job. Do you shoot her??

The crown stamp is a proof mark. The slide appears to be a genuine Colt, but the frame is not. I'm thinking that its worth about C$500.00 to C$750.00 tops.
Mismatched 1911's, P38's, and Luger's all attract about the same value concept. Not all original, but still a "shooter" and valued as a shooter.
