Well, the little "Ships Wheel" logo on the bottom of the side (under the eagle/shield/anchor) is the rating for Naval Quartermaster. It is reasonable to assume that DCF served as quartermaster then. There is too little information to do a computer search, but you may contact your local VFW and let them know you found the ring, and see if they may have a member who lost one. Maybe place an ad in your local Craig's list describing the ring (but not the initials and quartermaster logo.) If you get a response from DCF it should be an easy match. Best of luck, Sub
