I have a couple of caps. I think the shiny one is an early Rosemead. I am not sure if the dull one is original or not. The dull one is nicer made where the center ridge transisions into the rim. The teeth on the rim are also shorter and slightly angled out. The underside of the rim is also thinner. I have had both for at least 45 years. I am curious if I have an original???
