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.
