Bell's Royal Reserve
 

Hello, as I was cleaning out my recently deceased grandmother's house, I came across a bottle of Bell's Royal Reserve 20yr 43% blended scotch with a black label. The bottle was of the same fashion as the earlier Bell's rectangular bottles, except it had a Black label. I have been searching the internet looking for a matching bottle/label, but I could only find the white labeled bottles. Does anyone know the approximate year this was purchased? Thank you for the time.

We can probably have your bottle of Bell's dated for you, but will need for you to post photos. Let me know if you need help. ;)
