Published in 1950 in the USSR. This book is in Russian. I can't read a word of it. The title appears to translate into Russian Lighting Fixtures. I'm providing a photograph of the title page. When I first bought the book I tried to find another copy for sale on the Internet. I wrote on a little piece of paper that there was no other. That appears to still be the case, but it's hard to be certain of that. There is a section of text that runs from page 3 to page 34. Then there is a long section of numbered plates, 261 in total. That is followed by another section of text and another section that identifies all 261 plates. Then there is a Contents page, also some print on the verso, and what looks like an Errata sheet (although it might be something else) attached to the blank rear end paper. There are 273 numbered pages prior to the Contents page. At the front of the book there is a blank front end paper, then what looks like a half-title page.
