Welcome to the Forum. The star indicates a factory rework, usually but not always a refinishing; it was stamped so the returned gun could not be passed off as new.

Yours has a 6 1/2" barrel which was standardized at 6" not many years after it was made. It should not be used with high-pressure loads should you decide to shoot it.

If you post a Wanted to Buy ad here you should specify you are looking for "pre-war round butt hard rubber service stocks". Hope this is helpful.
