It could be from Boston, Mass. as a
[*]Whitwell, John P. ~ druggist & apothecary ~ no. 48, Newbury Street
is listed in the Boston city directory from the 1800's.
Which would make sense as it was found in New Hampshire.
Woody, I sold one of those about 3 months ago. I got it from an old estate in the Keene area, and it is the same size as the Liquid Opedeldoc and a few other cylindrical medicines that I think were produced in Keene during the 1830s.
Mine was the "ORIGINAL OPEDELDOC"... yours is IMPROVED!
Isn't this the same Whitwell who used the very attractive rectangular flint glass "Whitwell's Aromatic snuff" bottles?
Opodeldoc was a really widely used medicine in Britain and Europe as well as the US. But I think the liquid type was a US innovation that didn't travel back across the Atlantic. All the British and European opodeldoc bottles I've seen are wide mouth (like the one in the centre of the pic - the colorless one on the left is a Byam's) because the stuff used here was viscous and didn't flow easily.
