Hey CHK, It looks to be a dash plaque or emblem from a 1920's Dodge. Very common to find the emblems, but this is the first one i have seen fitted to a ring, looks way cool, and to find a ring the right size and shape is a cool thing aswell. A buddy of mine has a Mr, Horsepower necklace medalion that he had a jeweler turn in to a ring and it looks as if it started off as a ring, that is how good of a job the Jeweler did. Great score
