Bells's 12 Year Old

[Fixer]

I recently aquired several bottles of Bell's "Royal Vat Blended Scotch Whisky" 12 Years Old, in the distinctive green bottles. I know they are fairly old because they still have the unbroken federal tax stamps marked NY-I-313. Can you tell me anything about them?
I asked this question ubder Bell's, but probably didn't do it right.

Fixer - I can try to have them at least dated for you - can you post photos of your bottle? Be sure to include the closure and label (needs to be clear enough for us to read it). Let me know if you need help with the photos!

Thanks, I'll get some photos

I too would like to know about a bottle of 20 yr old .
But I can't add pictures yet. IRS label is NY-I-313
Serial no 506445867. Imported by James b beam import company.
Looks mouth wateringly delish.
