I was away from home but managed to order a few SB’s - couldn’t resist at that price

That’s amazing, I’ve said it many times before, you find the coolest and unique items    I agree with @mqqn I think an extra cork bottle stopper fits in that hole - is it deep enough ?

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!
