Help Identifying Johnnie Walker Black Label Bottle

[DeadHorse1134]

Hello first post. I would post pics but I can't put in attachments. The bottle I have is amber glass and its about 8 inches tall and 4 inches wide. It has a label at the top that says "Johnnie Walker Black Label". At the bottom it has a label with says "Extra Special Old Highland Whisky John Walker & Sons Kilmarnock Registered Produce of Scotland" There is also a coat of arms on the label that says "Confido" in The top label and "Gold Berry" in the bottom label. The bottle is shaped in a curved hip style shape. The original cork is down inside the bottle and is branded "Walker & Son Old Highland A.L. Whisky. I can't find any bottle like this anywhere online. Any Help dating this bottle would be greatly appreciated. Thanks.
