Curta Pepper Grinder Calculators

I’ve been absolutely fascinated by Curta Calculators for many years and would dearly love to get my hands on one.  They’re marvels of engineering – no batteries, no electronics, just beautiful metal and gearing work which you can take apart with a modicum of know-how and yet the maths power is amazing.    It’s a hand grenade shaped Difference Engine so you can see the appeal to anyone interested in code-breaking, cryptography and the history of computing.  They were developed by a Prisoner of War and the Nazis wanted to give final product to the Fuhrer as a gift.

(If anyone ever spots one in a car boot sale please, please buy it and sell it to me – I would love one but until I win the lottery just can’t afford to buy one)
