I bought it as a tool for use in car rallying, where one "handle turn" for each tenth-mile completed could display the scheduled exact due time.
The serial number is 510400, made by Contina Ltd Mauren in Liechtenstein and bought from ABM Automatic Business Machines Ltd of 11, Wyfold Rd, London SW6.
"I know the capacity that there is to make tyranny total in America and we must see to it that this agency [the National Security Agency] and all agencies that possess this technology operate within the law and under proper supervision, so that we never cross over that abyss. That is the abyss from which there is no return."
At 56, Admiral Jeremy "Mike" Boorda had everything to live for. As Chief of Naval Operations (CNO), he was at the pinnacle of his career. Supported by a loving family and widely respected as "an officer of legendary devotion to the Navy," why would the admiral suddenly and violently take his own life?
This small book is dense with well written content supporting the author's hypothesis that the is real. The author takes us on a brief excursion through European natural philosophy with stops at Descartes, Huygens, and Maxwell who also believed aether was real. The journey continues through Michelson and Morley, who's famous failed experiment proved that aether was not real (or at least could not be detected).
When I took my first 16 hour licensing exam in 1968 electronic calculators hadn't been invented yet, office type calculators were not allowed because they were too noisy, and slide rules were not precise enough, so almost all the applicants used CURTAs.
In 1972 I bought a HP-35 ( for about $400 - a princely sum) mainly because it contained the trig functions and I didn't have to carry the book of tables around any more.
So I knew that the Curta exists, and I looked everywhere in Holland and I advertised many times, but I seemes that there are no Curta's in Holland or people does not want to sell them.
I contacted the seller through the antique mall and found that the Curta was purchased by Raglind Binkley in Germany for her father, Walter Herrel, an electrical engineer working in South America at the time she purchased the calculator for him.
So, after watching several online auctions I got lucky and was able to secure a Type I Curta (clearing ring and handle in metal - silver subtraction ring) with a rather low serial number (11307).
It's not only my love of mechanical ingenuity that will keep me holding on to my jewels from our past that include a Halda Speedpilot and my abstract and ever-capable Curta, it's the fact that I have a "war wound" on my chin from the impact of my Curta clipping me during a M O N Y series event!!
I mean we wonder today about our current technologies which (so it seems) haven't reached their summit yet but the Curta was by all means one of the most intricate and elegant machines build by men for the sole perpose of crunshing numbers back in the days.
The Curta still works smoothly after all these years and has that common discolored spot from all the hours being held tightly as we bounced around the back roads of Northern California.
I was appointed to the Board of Licensing for Surveyors for the State of Michiganwhere I served for eight years; four years as the Chairman of the Board.
I must admit I didn't know there was so much information on the Curta out there and your site is absolutely amazing, has totally blow me away to see how many people enjoy this calculator.
