Can anyone identify what this grommet may have been on? Stamped JUAN GIRAL | MIRO. BARCALONA. I found it today in a farm field next to railroad tracks. Only thing I have found so far is a Juan Miro was an artist born in BARCALONA Spain in 1893.
This find was manufactured in Barcelona,Spain in the 19th century, the name of Juan Giral, a prominent businessman
I find these documents from a company called Juan Giralt perhaps the same factory but with the misspelled name (no surname Giral without T) I not sure that this makes only glass bottles http://pictures2.todocoleccion.net/tc/2011/01/28/24335687.jpg
