[DAL]

Hi I have an older miniature bottle of what I know as Dimple whiskey, The bottle is the dimple shape with wire around, but does not have the name 'Dimple' on it.I would like to attempt to date it.
Description:

It is the dimple shape bottle in clear glass with bubbles in the glass but no other markings.
It is approx 95mm high.
It has a gold color lead seal over what seems to be a thicker wire lid.
It has thin wire around the bottle.
It has three labels on it:
1Around the neck) JOHN HAIG & CO LTD, HAIG & HAIG LTD,MARKINCN, SCOTLAND, OWNING DISTILLERS
2Just below the neck) OLD BLENDED SCOTCH WHISKY, SPECIALLY SELECTED AND MATURED, BY APPOINTMENT PURVEYORS OF SCOTCH WHISKY TO THE LINE(? small writing) AND GEORGE VI
3lower down on the opposite side to label 2): DISTILLED IN SCOTLAND AND BOTTLED IN THE UNITED KINGDOM UNDER GOVERNMENT SUPERVISION.

Thank you.
