I came across a reference to this auction taking place on ebay at some point. It wasn't in the completed auctions.
It was for this:
Old Milk Bottle Deerfield NJ Ayrshire Mark Loper & son
I'm very interested in seeing this item as I had no idea my uncle had anything involving bottles, his brother-in-law was the glass factory owner. Then again, I'm not sure as to the date on it, so it could be his grandson.
