Type
I Curta Calculator
The serial # on this early Type 1 Curta is
39999. This
Type I Curta Calculator is in excellent condition and operates flawlessly.
The body is very nice and shows minimal wear or tear. There are minor
scuffs and losses on the outer metal case. The previous owners name
was professionally inscribed on the front below the Curta name. I
looked up the name and was surprised at how many people there are in the
world named Brett Huggins. In addition to the serial number the bottom of the calculator is stamped Made in Liechtenstein, by Contina AG Mauren, System Curt Herzstark. Case dimensions are approximately 4 5/8" tall by 2 1/4" diameter. The inside of the case has original pads top and bottom to protect the device.
The Curta calculator was invented by Carl Herzstark while imprisoned in a German concentration camp during World War II. This interesting design calculator was the top of the line manual calculator in its day and was immensely popular before the advent of the handheld electronic calculator which essentially made them obsolete in the 70's. In todays world they are at times used in road rallies and other applications but they are worth more as collectibles and examples of calculation history. The last examples were made up until about 1970 and all told about 150,00 both Type #1 & Type #2 models were made. They are highly collectible pieces of calculation history, and an important example of calculation technology in the scheme of things.

Thomas Edison's
Edison System Ampere Meter This Edison System ampere meter is a rare
and important piece of Electrical history. The condition of this large and
unusual Edison amp meter is exceptional. The scale
reads up to 264 amps, off the scale, indicating this meter must have been
used with a
huge dynamo or motor.This Edison meter measures approx. 10" across and 16" tall. The back of the case is cast iron. The etched glass face is flawless. The previous owner made a copy of the paper scale to cover the original scale to help preserve it. The original paper scale is behind the copy on the face in the pics. It is in nice condition.
The wooden case is original finish and in fine condition. The interior workings look like new. The wooden case is stamped in two places with Elec. Eng. Dept. L.S.J.U. which is Stanford University in Palo Alto CA.
A super nice and rare piece of American Electrical History that will display well and be a great addition to the old office, electrical, scientific or related collection! Nice!!

Electrical
World and Engineer Magazine January 18 1902
I have about 20 issues of this magazine in similar condition. The first
40 or so pages are all advertising. So are the last 10 - 15. The
middle discusses cutting edge developments in the emerging field of electricity
and engineering.There are ads for all sorts of rare things one could only wish to find. There are fans, motors, steam engines, light bulbs, arc lamps, telephone and telegraphy related ads, ads for tools and much more. The ads near the end mostly deal with larger things like steam engines, locomotives and large pieces of machinery and tools like milling machines, lathes and the like. Most all are in very nice condition noting the covers are very fragile and some are loose. The interiors on all are nice.
