Welcome to the Forum. You will get more replies posting in the Hand Ejectors 1896-1961 section, but from your description you most likely have a K or medium frame .38/200 British service revolver from the early 1940s. These were used in WW II by the Commonwealth nations (Great Britain, Canada, Australia, etc.), and not long after yours was built they became known as the Victory Model with a V serial number prefix. Some will call this a pre-Victory because of this. These usually had a 5" barrel (cylinder face to muzzle) and may have been bright or matte blue, or dull finished similar to Parkerizing.

Hope this is helpful.
