DOM of Colt
I've got a pre-war Colt Official Police,38spl. It was a state trooper sidearm. Can you tell mewhen it was made? The serial number is 56173x. There is a light D under the serial number on the frame, and there looks like ther is a T in front of the number that is high and to the left. These are only on the frame. The same number is on the crane, but nothing else. Thanks.
There are only two tools you really need: WD-40 and duct tape.
If it doesn't move and should, use WD-40
If it moves and it shouldn't, use duct tape.
