Hey guys, Have always loved Colts, have a 50's era Frontier Scout with buntline barrel and a 70's era CAR-15. The question here though is about the Police Positive that my cousin inherited from his grandfather. 38 special, the grandfather's original holster, 4 inch, not used much, probably issued between the two world wars, has "CAC No. 20" on the bottom of the grip strap. What do you think? It has holster wear and effects of long term storage without care, but it is not horrible- maybe 95% plus original blue.Anything you have would be helpful. The grandfather was said to have been issued this while delivering U.S mail.Thanks in advance.
