Does it look just like this one?Just bought an unopened 4 lb can of Unique - the label says "Hercules" rather than "Alliant", so it's at least 26 years old (likely older). It was priced right, so I figured it was worth the risk, guess we'll see...
I picked this one up about a year ago. Had to dig deep into the cash reserves to come up with $10.
I didn't tell the seller that I would have paid his $10 just for the empty can.
Getting the 4 pounds of powder for free made it a true bargain.
