"Une theorie de centrage des spiraux" by R. Boolsky, Phys. dipl. E. P. F., Geneve - Original magazine article (magazine clipping) which was removed from a 1956 Swiss magazine.
Text in the article is in French.
The opening sentence of the article reads:
"Le centre et l'origine du spiral
"Un usage plus que centenaire veut que l'on amene l'origine de la spirale mathematique a pas constant sur l'axe de rotation de l'ensemble balancier-spiral."
The magazine article was carefully removed from a Swiss magazine.
[Please note: this is a magazine article/magazine clipping only; no watch, clock, parts or tools are included.]
The article is approximately 3 1/2 pages in length (on 2 sheets of paper) and includes a few small black and white images within the text.
As with most vintage magazine clippings, there is some yellowing to the paper due to age as well as light wear and small bends.
The magazine article was carefully removed directly from a Swiss magazine. It is not a copy or reproduction. The rest of the magazine is not included.
