Well, it appears t be a .30 cal. model for the commercial market, probably mfg. during the 1920's. From these photos I don't see any problems. Finish appears to be original, and better than average.
A bit of paint thinner and a tooth brush may clean up the stains on the grip panels, but use great caution if you try to remove the left panel as it tends to chip under the safety lever base.
Congratulations, and welcome to the forum.
