I would say your looking at a range from $100-$125 for poor quality, all the way to about $400 if brand new in the box with all original grips and all. Hope this helps!
$400
1940
Made in 1934.
made about 1929
1931 sales@countrygunsmith.net
It would be 69 years old, made in 1943.
You will have to call Colt with the sn to find out.
I would estimate date of manufac. 1950
A bullet that has left the barrel has marks left from its travel down the barrel.
Serial numbers dont go that low on Offical Police revolvers. Need to know caliber,barrel length,barrel markings,etc.
No way to identify maker by just the serial number and caliber.
measure the barrel from one end to the other end. that is the length.............
