1Spectrograph (brass). Spectrograph was used on the Northwestern University's Dearborn Observatory 18.5-inch telescope . My notes from a telephone conversation with John Briggs (about 2008) are that he obtained it from Dr. Edward Liebhardt, president of a former diffraction grating manufacturing company in Woodstock, IL (WO)
