I knew there had to be a labelled one somewhere. This agrees with Fike. It doesn't say where it came from first though. Fike also says it was advertized in 1985, yup 19...85 by Medtech labs Cody WY. and introduced in 1891. I'm thinking typo 1895. Mind, I'm just digging for the truth and not trying to correct anyone unless it's me.
