Thanks for posting This is an unusual shape for this type of bottle often referred to as a "stone gin." Most often they are seen as tall cylindrical bottles but in this case the flattened sides seem to mimic a "case gin" Case gins are square-bodied glass bottles that were fitted to wooden cases for transport.
Your bottle is European and likely of Dutch origin. You may be able to use paper and pencil to make a rubbing of the embossing - this may help to identify the markings.
