Modern Electric Illumination (Modern Illumination Theory and Practice) by Henry Horstmann and Victor Tousley

In very good condtion - a little of the gold embossing in the title on the front page has come away  and is spread on the cover. 

I guess it's leather bound? The cover can bend, see photos. Red page edges. Many tables and diagrams.
