Yours is not listed in the blue book, however the one model listed, single action .45 ACP six shooter was made from 1984-1990 with a total production of 50 pieces. Very pricy and very scarce.
Worth doin more research, might be just pricy stuff or might be valuable stuff.
Sorry I don't have more......Sam
