This is a machine-made brown/amber glass bottle with a matching glas stopper, possibly used for storing medicine. The bottle was probably made in three pieces; there are mold seams running over the entire length of the bottle (body, neck and rim), although they are less visible on the neck, and around the base. The base is embossed with the markings "150" and "9445", which are most likely an indication of the content (150 ml?) and a number related to the mold, the production lot, or internal categorization by the manufacturer.
Using the Society for Historical Archaeology's online bottle dating guide, this one is definitely past 1940's, though I know too little still for a better estimate. (Maybe I'll revisit this as I learn more ^^)
