Black & White Whisky Bottle

[19lac67]

Hi I've just started collecting bottles since finding some cool ones in the Ottawa river. I bought this black @ whiskey bottle at an auction for 20.00 . How do I go about finding how old it . I have researched but cant fine the bottle I have. It also came with an open sleeve for it with labels bit rough. distillery glenuvet 26 1/2 ozes . the bottle is green in a flask shape with a metal cap with wire. If someone could steer me in the right way it would be greatly appreciated. He is what the front label says.
