Hi GTX, BB is correct my catcher is green and my chain case logo has the script Scott Bonnar with the red/white 45 underneath. I would be guessing mines a late 74' or early 75' model as it has the double brass id plates, I have seen some models similar to mine with the black chain case that have the brass top plate and aluminium bottom plate. I wonder if the wrinkle paint rusted through as there was no primer underneath, suposably hammer paint doesn't require to be primed if applied to bare steel. I hit mine with the engine enamel primer before the wrinkle finish, but as BB said funny how the inside stayed good after 45 years.
