Odhner Model 8 Calculator / Adding Machine
Item History & Price
| Reference Number: Avaluer:43833 | Maker: Original Odhner |
“Original Odhner” is the company that was formed in Sweden by the Odhner family after fleeing Russia following the revolution in 1917 and the nationalization of their company there. Willgodt Theophil (W.T.) Odhner, the inventor of the Odhner Arithmometer and founder of the company in Russia, had died in 1905. Original Odhner resumed production in Sweden almost immediately after arriving, and continued to produce pinwheel calculators until the early 1970s. With a s...erial number of 83064, this Original Odhner dates from approximately 1928.
This calculator works, but has quirks. The pin that retains the knob on the end of the operating handle has broken and the knob will slide right off. The carriage movement buttons don’t seem to want to cover more than a range of 3 positions. To move the input levers, you must release them with the small slide switch at the lower left of the levers. I haven’t run across this mechanism before. I also haven’t seen an Odhner with a switch to select multiplication or division (top left on the calculator). Needless to say, I’d need instructions to do a thorough test.
NOTE: A sharp-eyed and more knowledgeable collector pointed out that this is an Original Odhner Model 8, not a Model 7 as I originally listed it. I have changed the title of the auction to reflect this.
This calculator is from the collection of Robert K. (“Bob”) Otnes, PhD, one of the founding members of the Oughtred Society and the original editor of the Journal of the Oughtred Society. It is being sold by the Oughtred Society on his behalf.
The Oughtred Society was founded in 1991 by a group of slide rule collectors and is dedicated to the preservation and history of slide rules and other calculating instruments. Membership is open to anyone. Further information about the Oughtred Society can be found at: http://www.oughtred.org/.
PayPal is the only accepted form of payment. Buyers within California will be charged 7.25% sales tax.
Shipping will be by USPS Priority Mail. Shipping charges will be somewhat higher for destinations outside the USA.
