I think I have a Curtis and Harvey from my college years, but I might have tossed it. It is interesting I don't collect them, or at least I didn't until now. I just had a few with a little bit of powder in some lying around. The older one belongs to a friend. He is 81 years old but thinks it from the 60's.
It looks like your missing a Hodgen can which should go betweenDupont and Goex. Couldn't get Dupont for awhile in the early 70's. Curtis and Harvy was another popular type common. Ill post a picture if I can find em.
Did I get them in the correct chronological order except missing the Hodgen?
