Actually, there were lenses for THREE typewriters. Besides the Smith-Corona and the IBM Selectric models, there was a lens for several models of Royal manual typewriters. I know because I have one. I had it mounted a few years ago on the cover of the typewriter but so far I haven't gotten it to work right. Some day I will.
