I have owned three and jsut b ought a fourth MS 80 with the ad glass tops. The three I owned were all metal tops. There was a Conoco, Royal and Premium. All three were Conoco as you could see the outline of the pump plate on the pump. I will check in the AM to see what the one I just bought has for a top. A friend of mine had two fiber glass tops on MS 80s with the ad glass for Conoco. He said he bought them from a bulk plant that way. I assumed they were original as theyt pumps had been hand painted when they were still used and the paint slopped over so it looked like they had been together for along time.
