The first Enfield revolver dated to 1880- but there have been a number of models, You have to be more specific to get a more specific answer.
Your question is pretty much not answerable as asked. Colt has made many handguns in that caliber in different models and variations of models. You also did not provide the serial number. If you call Colt and give them the sn, they can tell you.
Your revolver was made in 1939. The Puerto Rico rollmark is especially interesting. All of the revolvers I've seen with that marking are Police Positive models, NOT the Police Positive Special. Two distinct models. You dont mention condition, which is the most important factor. The gun would be of value to a Colt revolver collector, but condition is everything.

Depending on condition, $300-$400. That is for the 1955-56 models- later models may be slightly less.
There were three American companies that marked a revolver known as "Secret Service Special." The Iver Johnson had a manual safety located on the frame. The H&R and the Meriden Firearms models did not. The H&R has a hammer-mounted firing pin, while the Meriden has a frame-mounted firing pin. They were made at different times, shortly after the 1900s- but despite the name, none were for the use of the US Secret Service.
