well the bottle looks like a pharmacy bottle, from the turn of the century, as far as the markings on the bottom im stumped, ithink i have a similar bottle, any help by the other members??
I have found some druggist bottles with the same thing on the base. Would guess that it is a mark from the glass company that made the bottles. I haven't found the specific company mark listed yet. I will post info if I find out for sure.
The base appears to have a "star within the crescent moon" trademark... The only reference I could find was to "Zenith" tools made by a Minnesota hardware outfit... Probably not related to bottle production or distribution...
