Company Names, addresses, dates1:
Washington Bottling Co, 465 Stafford alley SW (1910-1914)
This seems to be a short-lived company, as it's only listed in the DC directories from 1910 to 1914. They only made one type of bottle (shown below), although it comes in 2 sizes (7" and 7.5")2. It also has at least 3 known variations of the stamped lettering (slightly different letter sizes and arrangements)3. There are similar bottles from the Washington Bottling Co that are stamped with "BALTIMORE MD"3.
