Welcome to Treasure Net !!
Looks like a tall amber-glass oval-shaped vintage embossed whiskey bottle.
Can you take more pics of the design area?

it was to prevent bootleg wiskey makers from pouring their home made booze into the bottles or other "legit" liquier companys from reusing the bottles - and filling them with "untaxed" liquier . --booze bottles were to be one use only by federal law.--bottles marked this way are from a certain tiime frame.
This appears to be the same bottle as yours--perhaps it is yours! http://www.ioffer.com/i/20256556
If not, what are the words, letters, numbers, images that might appear on the base of yours?
