Kepler bottle with pontive

[AntiqueMeds]

That base indicates a cup mold probably from a few years into the 20th century , assuming its handblown (is it?).

I am new to this and not sure how to tell if hand blown can you help?

Hi Greg, welcome to the forum!
The mark on the base could be an "Owens ring" which appears on many early machine made bottles.. named after the Owens Automatic Bottle machine, which revolutionized bottle production at the beginning of the 1900's.. you need to check the mold seam.. if it goes all the way up to the top of the lip, it's machine-made..

There seems to be a seam on the neck and around the base of the neck but nothing on the bottle its self.

 

[AntiqueMeds]

on a square or rectangular bottle the seam would be at the corners and hard to see.

try this link if it works...

Ah yes thanks for the help there r two seams down two corners, I imagine this would make this bottle of little value?

 

[woody]

Yes, Greg. It probably has very little value, monetarily wise. Keep looking, though.[]

Not worth much but consider its still probably close to 100 years old so still interesting.
