Here is an easy question for you historians: When were the paper Stamps/Seals across the caps of Whiskey bottles discontinued? I have some bottled in bond bottles that were bottled in the early 1980's that have these seals that state "United States Government supervision, bottled in bond". On these the year made and year bottled are printed on the same seal. (very helpful) On other bottles, the inscription "Tax Stamp, US Internal Revenue Tax Paid" or "Manufactured in accoudance with US government regulations". On these later stamps, no date is given. The presence of the stamp itself should give some indication of age if I knew when this practice was current.
I know this is an elementry question, but still of good use to us newcomers.
