This webpage serves as a display of my collection of older calculators and related things.

The site is not finnished and I will add more calculators as I find the time. In the mean time, if you have any requests or questions regarding specific calcultaors, regardless if they are displayed on this site or not, don’t hesitate to use the contact details found here!

Several of my stationary mechanical calculators either are in need of restauration or have already been restored. I am no expert in the area but if you need advice or reference pictures for reasebly I would be more than happy to share if you ask!


Mechanical: Stationary

My collection of stationary calculators, including brands such as Facit, Original Odhner, Walther, etc.

Mechnical: Handheld

My collection of handheld mechanical calculators, including brands such as Addiator, Produx, Record, etc.


Not an official collection but if I stumble upon one I might buy it from time to time.


Instruction manuals and Brochures – Coming soon

I actively collect manuals for both calculators that I own and those that I don’t. I also collect brochures and other printed matter related to (mainly) mechanical calculators.

I would like to digitize and publish them on this site but I am currently unsure if it would be legal, but I will look into it when I get the time. In the meantime, if you have any specific requests please get in touch.

Marketing and brand related – Coming soon

Things related to calculators and associated brands.

Mechanical Stamps – Coming soon

I also have a collection of mechanical stamps that I plan on adding to the site, but I will prioritize to add my calculators.
