Not much information to work on, but Smith & Wesson made the Military & Police revolver for many years, and now make an auto pistol using that designation.
The metal ring on a pistol or revolver is called a lanyard ring. A lanyard is a piece of thin cord, that clips to the ring, and then is looped around the shoulder, usually as part of a military or police uniform. It's been a while, but US and UK military police used to use lanyards as part of the military uniform from about World War I to the recent past.
Colt M1911 chambered with the .45 ACP. No pistol has been made that is better than the original Colt. Still used today by some military and police. The Smith & Wesson K22 is the best revolver ever made.
Many civilians, police and military.

A good starting point would be to contact Webley & Scott- they are still in business, have a website and an email contact on their site. There are at least 3 handguns that may (at a stretch) fall into the category of a Webley & Scott .38 pistol- the Webley-Fosberry Automatic REVOLVER (somewhere between a revolver and an auto pistol) the Webley Metropolitan Police auto pistol in .380- but I expect you are looking at the W&S Military and Police in .38 Auto. These are rather scarce, made in the early 1900s, and only for a brief time. Sales seems to fall in the $2500-$3000 range. See link below for a picture-
Depending on condition, your Charter Arms revolver is worth about $180-220.

Military police officers wear military uniforms.Added: Displayed on the military uniforms of their particular branch of service are badges, similar to civilian police badges, and/or they wear armbands or, sometimes, distinctive hats or helmets, and/or white pistol belts, so that they stand out from the usual military uniform. And, unlike other member of the military outside of a war zone, they are always armed with a sidearm
