The University of New Mexico runs the Capilla Peak Observatory in addition to a small campus observatory. The Capilla Peak Observatory contains the 24 Inch Boller and Chivens telescope.

In 1970 the 60cm (24inch) Optical Craftsmen (the ‘OC’) telescope was installed.
Five years later a second 60cm telescope made by Boller and Chivens (the ‘B&C’) was erected. The Observatory now operates entirely as a field station of the University of Canterbury’s Department of Physics and Astronomy.

Hoher List Observatory is an astronomical observatory owned and operated by Astronomical Institute of the University of Bonn. It is located 60 km south of Bonn, Germany, near the town of Daun in the mountain range of Eifel.
The University of Bonn website has information about this observatory but the website does not translate well into English.
24 Inch (.61 meter) Telescope for New Mexico State University Observatory
From NMSU website.
New Mexico State University runs Apache Point Observatory which operates four telescopes but also owns a 24 inch reflector on Tortugus Mountain. This telescope has been used for planetary observations and observations of the Comet Shoemaker-Levy 9 and its impact on Jupiter.
This is a very interesting story of the history and renovation of the 24 Inch telescope and Tortugas Observatory.
And here is a video of the restoration:
24 Inch (.61 meter) Telescope for Mount Stromlo and Siding Spring Observatories, Australia

In the early 1960s, the Australian National University established a new astronomical site at Siding Spring in central New South Wales, partly in the expectation that it would provide somewhat clearer skies than those at Mount Stromlo, and partly to escape the increasing light pollution of the growing Canberra. The selection of Siding Spring followed an extensive site-testing programmer organized by the then Director, Bart Bok. The new site was instrumented with three reflectors of modest size, all made by Boller & Chivens. The 40-inch is the larger of these, the other two being a 24-inch and a 16-inch. It has proved a useful instrument especially for photometric and imaging work.
24 Inch (.61 meter) Telescope for Lowell Observatory
The current location of this telescope has not been identified. Over the years there have been many telescopes in operation at this observatory and many have been donated to other research institutions.

24 Inch (.61 meter) Telescope for Mees Observatory, University of Rochester

The Observatory houses a 61-cm Boller and Chivens Cassegrain reflector, dedicated May 8, 1965. In March 2000 the telescope was upgraded to computer control by DFM Engineering. The Mees site enjoys very dark skies, with the best weather being encountered in the summer months.

In 1971, Van Vleck Observatory acquired the 24-inch (0.06 meter) Perkin reflector telescope. Boller and Chivens, a subsidiary of the Perkin-Elmer Corporation, manufactured the 24-inch telescope for Mr. Richard S. Perkin in 1966. After Mr. Richard S. Perkin’s death in 1969, the Perkin family donated the telescope to Wesleyan University.
