Your "Spring-cap " bottle should date to between 1930 & 1960...this is the period the
'spring-cap' bottels were made by Haig & Haig.
The are some slight variations for each of the brand lines Haig & Haig products, such as
Pinch/Dimple, Five Star, Black & White, etc....but they all run about the same time period.
It would behandy to know which Brand of bottle you have, and as is always suggested on
whisky.com...Photos are a fairly critical element in dating a bottle.
Subtle changes in label design & wording used, along with notations of Royal Warrants,
and particular bottle design & neck sahpe are all important factors to consider in dating
a bottle for you.
If possible, send in a few clear pictures of the bottle showing the full bottle, and close-ups of the front label, and we should be able to get you with a 5-7 year date span.
*Additional dating can often be refined if we can see detailed photos of the Bottom of the
bottle, and any Tax Stamps/Seals applied to it.
