OLD COLT

[Ursus]

I have an old gun that belonged to my father. It´s a 6¨.38 spl. Colt. As it has been refinished -nickel- there are no markings on it but I´m pretty sure it´s a Police Positive Special. This is the first gun I ever shot,and it has a special value to me. I was wondering the aprox. date of manufacture. Serial number is 354383.
Can anyone help?
