The Great Paris Exposition Telescope
“The Great Paris Exhibition Telescope with a 1.25 m diameter lens was the largest refracting telescope ever constructed. When the year-long exposition was over, The company which had organized in build the telescope declared bankruptcy and were unable to sell it. It was ultimately broken up for scrap; the lenses are still stored away at the Paris Observatory.”– Wikipedia
