Twitchell, Champlin, & Co., ca. 1881-85 etc. was located at 252-254 Commercial st. at Merrill's Wharf. They were a wholesale grocer and bottled extracts to start, but then opened canneries in 1903. (www.mainememory.net) There is a photo at this mainememory site of the original store.
This bottle was from 1881 to very early 1900's. In 1903, Twitchell-Champlin Co.'s started a canning business. By this time they were putting out a million cans a year. They canned vegetables and fruits. In one year 12,000 bushels of apples were canned at their one plant located outside of Portland, Maine in Wolcott. They also canned peas, corn, string beans, strawberries and raspberries, all grown in Maine.They increased production and then operated numerous (over five) canneries outside of Wolcott Maine, including large canneries of fish in Maine. They were considered a large wholesale grocer of Maine. W. A. Buckminster was the first manager of the Wolcott factory. He was born in Stonington, Maine, November 16, 1863. (for more information see page at: http://fultonhistory.com/Fulton.html. for search of "Grips's Historical Souvenir of Wolcott") You can see a photo of their first cannery at this page.
At books.google.com you can view an original advertisement for TWITCHELL CHAMPLIN NEURALGIC ANODYNE from JULY 1906, The National Magazine, Vol. 24, Issue 4, page 486. You could buy a bottle for 25 cents.
Here is what it said on the paper label noted in the advertisement: "It stops pain if taken internally or applied as a liniment." "Quickly stops all pain and relieves the pain-racked sufferer. The family medicine chest should never be without it. It is an invaluable remedy in case of sudden need." "Ask your Dealer for it, and see that you get Neuralgic Anodyne." "25 Years of success proves its worth." "Price per bottle 25c." I noted the face of a young girl (looked like an older child or young woman) in the advertisement.
Based on this advertisement the product was '25 years' success. The ad was from July 1906, so that means Twitchell-Champlin started this Neuralgic Anodyne in the year 1881.
I am left wondering what the ingredients were! Most likely can be found in a patent, perhaps.
Here is the link to the advertisement. If it does not work seek it at the above mention via Google to view.
