Very cool new addition!!

Jimmy, I compared all the Stains on the pic of your Jug using my copy of Barrels & Bottles & Tennessee Jugs and found the Stains All Matched Exactly and with The Handle being on The Right, I would say with No Doubt, you have The Jug that is pictured on Page 1 & 11 in Barrels & Bottles & Tennessee Jugs  Congrats on your Find and Discovery,   Roy

Nice!  I bet it was a cool stopper for those nice corked bottles.  Another great find, Jimmy! 

Beautiful!💯

Beautiful jug Jimmy and wonderful find! You are very lucky 😉
