Cool. It's the first full bottle I found up there. Had no idea what it might've been used for since there's hardly any room for anything to fit in it. If it is around 1890 then that kind of goes with the period this cabin was used up at the mine
Opium came in tins which are/were found anywhere that had a community of Chinese people in the old days.If you"ve been diiging in trash dumps where there were chinese rail workers,miners etc you'd find lots of crushed opium tins.
