I was rather sloppy with my slashmarks,
the proper order for the embossed mark on the aqua glass pharmacy bottle is:
"H.H.H. HORSE/MEDICINE//D.D.T. 1868///18 F"
Fike shows the "18" on the base as an identifier for Indianapolis and also Chicago manufacturing cities.
Rough dates are 1874-1920's for the site.
I will hopefully get pictures uploaded to a page later tonight.
Thanks, Suzanne
