Holy shit! A real one?
Yup! SN 528128 Got it off eBay. Apparently the previous owner passed away and his daughter sold it. Paid $1300 for it. It's the dumbest thing I've ever spent that much money on and I regret nothing.
It had some issues when I got it doing division. It tended to jam up turning in reverse. But I was able take it apart to get it working. One of the metal tabs wasn't bent quite enough. Makes sense since these thing were all hand assembled and tuned.
I looked up the serial number on curtamania, and saw some checkins from various previous owners. It was pretty wild that someone even uploaded a photo. Not of a Curta calculator, but my Curta calculator.
That's cool as fuck. I showed this to my fiancée but she didn't seem to understand how cool this is.
I also have a much cheaper mechanical calculator, one of the ones you dial in the numbers with your pencil and only goes up to 9999 before the digits overflow. When I get up in the morning I'll see if I can find it.
