I suspect this is an oil or vinegar product bottle but am not certain. It is machine made, it is earlier 20th century, as you say it has a distinct art deco appearance. It reminds me of the style of a designer named E. W. Fuerst who worked for Owens-Illinois who filed a number of bottle design patents.
At some point I will make public my database of bottle design patents - currently it is a work in progress, never seem to find the time to roll it out to my website.
