Here is a rare and unusual dark amber glass bottle showing marks from a three-part mold, and a 'cork' style top.
It might have been a laboratory or pharmaceutical bottle, or perhaps even an unusually-designed beer bottle (!?).
It measures 5 inches tall, by 2- 3/4 inches in diameter. 

This bottle is in excellent, used antique, condition with no chips, cracks, or other damage, or repairs. It is clean and bright with minimal surface wear. (See photos).

Shipping within the continental US only, will be $13.89.
I do not ship directly outside the US. International buyers must use eBay's International Global Shipping Program.
ATTENTION CHINESE BIDDERS: I do not ship directly to China. I will be happy to ship it to anyone in the continental US who is willing to then ship it on to you. Sorry for any inconvenience.
I only ship on Fridays or Saturdays. 
No returns PERIOD. I have excellent feedback, especially concerning my accurate descriptions and clear photographs.
Payment must be received within five days of purchase date.
