Notes:
Samuel Farber was born 1880 in Poland, and came to NY in 1903. He came to Washington DC in 1910, originally as a grocer but later became the proprietor of a bottling company. He retired in 1940.
I find it currious that many Farber bottles turn purple (Sun Colored Amethyst), which usually indicates that a bottle was made with Manganese, which was supposedly discontinued around 1915. Did Farber's bottles continue to use Manganese in the 1920s after everyone else had stopped, or was Farber making bottles before 1920?
Note that the first address I have for the Whistle Bottling Co was in Alexandria VA. The Rammel Mfg Co. was at that same address in that same year, so I don't know if they were connected. I'm also not sure if that Whistle Bottling Co is connected to Samuel Farbers Whistle Bottling Co. Whistle appears to be a national company that originated in the mid-west.
