DANSALATA,thank you for the feedback. It seems that the J. Walkers Vinegar Bitters were produced and consumed in California. The question now is how did this bottle end up in a shipwreck in the South Atlantic ocean? The Panama Canal did not exist yet at that time, so, where was the ship heading for? Did it come from California, around Cape Horn, heading for the east coast of the USA?The shipwreck dates from about 1870-1880. Part of the cargo seems to be a whole train.Below picture of a glass jug from the same shipwreck.
