Bought these at an estate sale, told they were hood ornaments.  They look like the Ducks Unlimited logo but there are no markings on these.  They could probably be used for a number of things: handle, knob, art project, decoration, hood ornament, etc.  They have a threaded hole in the bottom and I've added a bolt for each so they can be mounted.  They are solid metal and weigh about 6 ounces each.  These were painted to look like male and female mallard ducks.
