<p>[QUOTE=&quot;all_fakes, post: 127958, member: 55&quot;]Another site lists this as the A.W. Faber model 375, from 1932, made in Bavaria; the company had by then adopted the name Faber-Castell, and sold their products through a great many retailers; I think MDS (England) would have been the retailer for this one.</p><p>See <a href="http://www.sliderule.ca/faber.htm" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.sliderule.ca/faber.htm" rel="nofollow">http://www.sliderule.ca/faber.htm</a> and also <a href="http://www.sliderulemuseum.com/Faber.htm" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.sliderulemuseum.com/Faber.htm" rel="nofollow">http://www.sliderulemuseum.com/Faber.htm</a> for some comments and additional photos of this model.</p><p>&nbsp; &nbsp; For those unfamiliar with the concept, a slide rule is a simple device which uses sliding scales to add numbers; and as discovered centuries ago, one can perform multiplication by adding logarithms.</p><p>Per Wikipedia, &quot;Before the advent of the pocket calculator, it was the most commonly used calculation tool in science and engineering. The use of slide rules continued to grow through the 1950s and 1960s even as digital computers were being gradually introduced; but around 1974 the handheld electronic calculator made it largely obsolete and most suppliers left the business.&quot;</p><p>&nbsp; &nbsp; Kind of sad that nobody today is taught how to use these interesting devices.&nbsp; See <a href="https://en.wikipedia.org/wiki/Slide_rule" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://en.wikipedia.org/wiki/Slide_rule" rel="nofollow">https://en.wikipedia.org/wiki/Slide_rule</a> for an article on slide rules and how they were used.[/QUOTE]</p><p><br /></p>
