Antique Pin-Wheel Calculator / Arithmometer

Grimme, Natalis & Co, Brunswick

Circa 1920s

Fantastic example of an early 20th Century Brunsviga pinwheel calculator. 

The calculator is in good condition and is set on its original wooden base. The black-enameled casing is in quite good condition and the metal component parts are well preserved and show off a nostalgic aged patina. 

At the top of the machine is the brand name BRUNSVIGA System Trinks and a patent stamp. On the base is a metal plate with the name and address of the shop where the calculator was once sold: "Block & Anderson Ltd. London & Cambridge". There is also a serial number Nº 54649 on the machine.

It is being sold as seen however I have tested it and as far as I'm aware it appears to work as it should.

 

Approximate Measurements:

Base : 14 1/2" (37cm) x 7" (18cm)

Height : 5" (13cm)

 

The best description comes from the photos so please look at them all carefully and if you have any questions please ask.
