Hey James, I wanna see bigger and better photos of that, please, from multiple angles. Looks very cool. There's an ad with a picture on page 111 of the "Advertising Department" near the bottom of the page of this 1862 Toronto Directory: http://static.torontopubliclibrary.ca/da/pdfs/37131055376883d.pdf listed under Cutter & Tower Co., Stationers & Paper Dealers, 89 Devonshire St., Boston.
"Barometric Ink Stand, patented 1861-67
by Thomas Hudson, advertised 1878-81, still marketed in 1905. In 1905, it was manufactured by Cutter Tower Co., Boston, MA, which said at the time that the inkstand had been sold continuously since 1861." http://www.earlyofficemuseum.com/Pens.htm
