Haig & Haig

[w0wbagger]

I was unbelievably lucky today and managed to buy a case of Haig & Haig Whisky at a charity auction. It was still in its case, wrapped in paper and hay, and consisted of 12 bottles. I've attached a couple of pictures of 4 of the bottles. Does anyone have any idea of the age of these and/or their value? We opened one of them and the whisky was great. Are these blended?

Thanks for any information you might be able to provide.
