Antique Labeled Ink Bottle/Jar "Barnes National Ink

Up for bid is an antique labeled "Barnes National Ink" Jet Black bottle/jar/ink well. I'm not sure what to call it. We found this in the attic of our home which was built in 1891. There is no date on the bottle. It appears to be hand blown as you can see the bubbles in the glass. It is approx. 2.5" high and the bottom diameter is approx 2.5". Winning bidder to pay $6.95 priority shipping. Have a great day and thanks for looking!
