Since they were made in a permanant mold, that would put them in a semi modern date, maybe 1800 and up. If you could see a mold line up near the top of the neck, 1900 and up. Pretty cool that the corks are in them. Must have been in a calm muddy bottom like a bay. Hard to say what they held, most likely wine? Maybe a look at the bottom the see a pontil or if there is any writting. Shouldnt be a pontil if fully molded, which I am sure these are. And as for the lions flanking a shield, you would think Europe, could be anywhere there, but it also could just be a family crest. So that really doesnt help. There were lions flanking shields all over. Without the shield details, cant help. Custom, fancy decanter type bottles are very hard to date, because they could have used old methods, It would be a lot easier if any regular type bottles were found with them, such as the black clyinder 5th of whisky that is so common. Maybe it was a whole load of these. Any other items?
