Remington Rand 73P
Bought on a flea market in Antwerp. My first mechanical calculator - very cheap, and the owner was glad to get rid of it, no doubt with the prospect of having to drag it back home. Despite not really being my piece of cake, since it is not a four-species calculator, I decided to keep it because it was my first machine, and also because of its beautiful design, with the black crinkle finish, yellow keys and wooden crank knob. It looks very fetching in a late 1940's kind of way.
