The intricacy of machines made in those days is amazing and artwork within themselves.

Beautiful reproduction, I love mechanical calculators and didn't now about this machine so thanks for making me descover it

[@ClanMcDuck]

Amazing. Beautiful. Even the sound is lovely! I'm so impressed by the ingenuity and engineering of these type of machines.

Wunderschön! Der deutsche Erfindergeist.

It's a giant brass Curta :)

unglaublich cool! Ich libe es!

[@ronliebermann]

It would be nice to see a documentary about the watchmakers who originally developed the manufacturing techniques for mechanical calculators.

[@MarkFrankclocks]

Agreed. There are many sources for the development of horology and the matchmakers. Few of the early calculators give credit to who the watchmaker was, if that was an independent one. Philipp Hahn, for example trained his protégés.

Looks like a giant Curta.

[@XMarkxyz]

I was about to say the same, the working principle is very similar, at least on a superficial level not sure about the more inner workings like carry etc.: I guess that going from a popularity to a historical point of view we could say the curta is a miniature of this machine

[@jeffarmstrong1308]

A new acquisition, Mark?

[@MarkFrankclocks]

I'm thinking about it. I've just become interested in these calculators, as if clocks weren't enough of an obsession! Here's a link to my website featuring two I've just bought: www.my-time-machines.net/other_horological_examples.htm

wouldn't doing basic math on paper be faster?

ENIGMA :D
