Notes:
Samuel Claxton Palmer was born 1839 in Washington DC. He started as a clerk in May 1861 working for Arny & Shinn's bottling company at 57 Greene Street in Georgetown. In 1871 he and Robert M. Green purchased the bottling company from Riley Shinn. In February 1874, Green withdrew from the company and moved to Philadelphia, leaving Palmer as the sole proprietor.²
In 1884, Palmer bottled lemon soda, sarsaparilla, ginger ale, and other carbonated beverages, and was also an agent for both the Wm. Massey Brewing Company and the Jos. Schlitz Brewing Company. He employed 35 to 50 men and boys and had 12 to 15 wagons to deliver goods in that year. ²
I assume that his address of 57 Greene Street in Georgetown changed to 1224 29th Street in 1881 (i.e. that wasn't a different building, but was a re-numbering due to the renaming of "Greene street" to "29th street").
Palmer's bottling plant at 1066 32nd street NW, which was later designated as 1066 Wisconsin Avenue after a street name change, had previously been a fire house.

I beleive it was written by Samuel Palmer to his father, because it was signed "yours, Sam". Also, the 1850 Census lists Palmer's father's occupation as "Merchant & Carpenter".

The center bottle shown to the far left was made from a mold that had the word "GEORGETOWN" peened out and the word "WASHINGTON" engraved above it. It doesn't show up too well in the photo, so I took a rubbing of the bottle (shown to the immediate left). I photographed the 3 bottles to compare them. The word "GEORGETOWN" on the left bottle is lower than the word "WASHINGTON" on the right bottle. Georgetown was assimilated into Washington DC about 1880, and Palmer opened up a 2nd bottling location that was outside of Georgetown about 1888 - so this bottle was probably from about that time period.
