It is a 500 Sportsman. The year is 1953. I forgot the month but it is stamped on the fount. It should fire right up. There is a lever under the burner, one side for light and the other for when it gets going. It takes a while for all that cast iron to heat up but when it gets hot it burns real nice. It does not like drafts. There was a sheet metal wind deflector the goes around the posts for the grill. I might make me up something some day for mine.
