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

[Skywalker]

Without a mark on this gun from where a SN would have been I can only assume it does not have one and maybe it did at one time but don't feel this was ever a illegal thing going on. Maybe back then they didn't care to change something out and explains the SN written on the paper within the grips. I hope its not a problem for me to own my dads possible service weapon without a SN.

I believe they did all have serial numbers but they were not always unique between models. When you do a serial number search on a early 1900's you may have 10 possible matches. They did finally start using unique ones in the 30's perhaps I don't recall. The Police Positives can be hard to id as barrels were swapped routinely. Making it even difficult to determine caliber.
