Are there imperfections to the glass? Any bubbles in it? It's so dark my old eyes can't tell. Also, is there any chipping inside the mouth of the bottle? Is it threaded for a cap? Again, I can't see it well enough to tell. With bottles like this it could really go either way. A resurgence in the old style jugs and what not has been pretty common the last decade, therefore many modern bottles are made to look old. Where did you find it? This could possibly give us a clue.
From my knowledge of bottles I do know it is a older bottle for sure
No threads bottle glass is wavy and has imperfections
I think it may be a two piece mold seam stops at bottom of neck
Yep, now I'm with you. I see the dots too in the new photo. The color seems unusual huh? Very, very nice. Im not entirely sure, but I believe you're right about it being old. Perhaps a syrup bottle?
It's very difficult to tell without seeing it in person. If there's a seam that runs down the side, it indicates the bottle was machine made, rather than blown.(AFTER 1900) Usually bottles of the 18th and 19th centuries lean to one side or the other. The necks tend to not be straight up and down. The lips can vary, but usually are pretty crude looking. I know a lot of Pier One bottles, are made to look like Antique bottles. Here's some samples of really old ones. https://www.google.com/search?q=18T...QsAQIKA&biw=983&bih=707#imgrc=nvxv49MTI7YAuM:
