This is an ink bottle probably a little larger than actual size, four inches total, found in a hole in England.
Dating from the 1890, which is like a century, blown glass, BIM, the bottle people call it, for blown in mold. .
Bare, Morecambe Bay, United Kingdom according to eBay description page whence these photos, a dreary place, the bay, according to Google images, but thank you for digging up this bottle I do appreciate all the digging.
This is the hole.
Anyway it will make a super hummingbird feeder. I think.
For the wayward wandering hummingbird during migration, not for a steadily active hummingbird area. It would be too small for that. But this is the ink bottle that I've been waiting for and had to out-bid other people for, sorry to disappoint them, but I needed this unique bottle for this specific thing.
