Found these on my job site. For you who dont know I dig out 8ft of dirt from under 100yr old house in Alameda ca and redo the foundations . That's why I'm always fi di g bottles or marbles . Thank you to all of you for Sharing knowledge about these bottles much appreciated.
It's a construction find I work for the 1 foundation company in Alameda ca . So when digging out the foundations we always find stuff like that .and the guys I work with will put them aside for me if I'm not present. Pretty cool I think
