Well look at this, Bettye Jo. It is referring to Publicker Industries which is who Grandpa Bryant worked for in Pennsylvania after he left Lawrenceburg, KY.
"They were probably also the suppliers of rye whiskey to Merle's Standard Distillers in Baltimore, for bottling Pikesville "Maryland-Style" Rye after their regular provider, Majestic Distilling in Lansdown, Maryland, ceased production in the early seventies. Heaven Hill, the Bardstown, Kentucky company that purchased the Pikesville brand in the early eighties also bought the Rittenhouse brand at around the same time -- and they bought it from Publicker/Continental."
HH bought my granddaddy's whiskey. Well, it wasn't his whiskey - he just bottled it. ;-)
