I believe I have several of the later style. There were about 5 or 6 styles made for model A's. I believe that the later, more common style was used from 1929 through 1931. The differences in the 1929 to 1931 styles were very minor. There were 2 styles made for 1928's and the forging were made different from the later ones. I can check my storage for a good one if you want me to. I think I have one sandblasted and painted black, but I would need to check for sure. It would be $25 plus shipping.
