Colt Revolver... Help Identify Model, Year & Maybe a Value

[Skywalker]

This was my dad's whom passed away back in 05. This Colt is old and I don't really know what its worth or what year it is. Anyone like to help out with a littl info on this gun.

Only markings are:

No Serial # which does not make since. No grinding anywhere so did Colt make revolvers back in these days "what ever year that may be" without Serial #'s?
Colt?s PT FA MFG CO HARTFORD. CT. USA.
PATD AUG 5, 1884. JUL 4, 1905. OCT 5, 1926

There is the Colt horse on the left side and of course on the handles. There is a whole in the very center and bottom of the butt end of the grips for lanyard. There is also an old small piece of paper inside the handles that looks to be 100 years old with a set of numbers on it. Maybe ?According to Geraldo? this was from Al Capone?s Vault!

SN not under the grips stamped on the frame. Also not on the frame anyplace? No caliber stamped on the bbl?

No sir and no sir!

What caliber?

That gun should have a SN. I haven't owned a Colt revolver in years but maybe somewhere on the frame.

Looks like a Colt Police Positive Special:

According to the wiki, Colt's most produced DA revolver, made from 1908 to 1995 (wow I didn't realize they made them that late!)

According to an online source, if it's a Police Positive the SN should be on the frame where the crane swings out.

Actually, looking at it closer it seems more likely to be a Colt Official Police:

Serial number should be in the same place. Swing the cylinder open and look on the frame where the crane swings out.

Very similiar for sure except the grips and I'd say that could have been a variance to each model for personal perference. Thanks.

Looks like a New Service to me. But it's hard to tell how big it actually is. Is this a large frame gun or smaller frame? The hole in the bottom of the grip frame is for a lanyard loop.

Bailey, I think I'd say its a large frame or med. Its not what I consider small at all.
