Uh, going by the Hunn book, a 499 is either a ’37-’38 4.2 horse or a ’39 5 horse which I believe are the same motor except for the power rating. I’m betting it’s a ’39 as it looks identical to a couple I have and the 39’s seem to be more common. But then again, with that fairly low 440 serial number, it could be a 4.2 horse.
