Odhner Model 30 Pin Wheel Calculator
Original Odhner Calculators went through many modifications over its lifetime. The
basic design idea was first introduced in the 1870s. The design and name
changed several times over the years. One of the best sites to read about and see
many different models is John Wolfs site,
http://www.johnwolff.id.au/calculators/Odhner/Odhner.htm
He does not list a Model 30 but has a No. 29 he dates from 1938, and this
Model 30 seems to be a very close match. The cosmetic condition is
very nice. A look back into the past.

These are almost always missing as they do not fit well in the box Thatcher
calculators came in and so got separated. Minor stains and some
looseness to the binding, but overall very nice. Click for Pic Click for Pic Click for Pic

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!!

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.
