Antique Bottle Gin bottle Green - dump dug glass

A deep green dump dug gin bottle in nice condition.   Some discolouration on the glass inside.   See pictures.   The top is not broken or chipped.   It appears damaged in the photos but that is part of the blob on the top.  An indentation on the bottom of the bottle.   Comes from King Williamstown Eastern Cape.   Please feel free to ask questions.
