Notes:
They apparently had a Washington DC branch. Their location sure moved around a lot. They didn't adopt a single bottle design like coke did until about 1940, although the drum style bottle below was used a lot.
I don't have any directory information past 1975 yet.
The 1962 directory said they bottled: Pepsi-Cola, Teem, White Rock, Schweppes Beverages, & Fountain Syrups.
