Hi and thanks for posting all the photos.
My hunch is that this one is about 100 or so years old. I would have a better feel if I were holding it and could get a close-up look.
A large number of these bigger bottles are making their way over from Europe. I am not entirely sure how long these were made into the 20th c. but I do see enough with the wicker still in place and other visual clues that suggest perhaps they were made further into the 20th c.
Wicker or other woven covering is the reason so many of these have survived in such great condition.
There was an article in a recent issue of Antique Bottle and Glass Collector on demijohns. I will try to find that and revisit to see if I can expand on my answer...
