Hi everyone!
I found this small amber glass bottle (about 5–6 cm tall) on an old rural property in Espírito Santo, Brazil.
The bottle has:
a short neck with screw threads, flat-round body, and embossed “8 SM” on the base.
I’m trying to figure out which manufacturer used the “SM” mark and what kind of product it held (ink, medicine, perfume, etc.).
Any info or photos of similar marks would be greatly appreciated!
    Thanks !
