A Swiss amateur astronomer Mr A Maurer completed a general catalogue of Herschel's telescopes. According to the summery published in Issue No 14 of the Journal of the Antique Telescope Society, the 49 telescopes are classified into the following three groups:

1. Telescopes for observation by W Herschel himself or Caroline (8)
2. Telescopes made by Herschel for sale to the persons who had an interest (33)
3. Telescopes which important parts such as optical parts of were supplied by Herschel or telescopes made by other persons under Herschel's guidance (8)

Here I extract only 7-foot telescopes, which are the same type as Herschel discovered Uranus, and make brief notes on them. (Please refer to the table in below.) There are 26 telescopes; 2 (A5-A6) for the above A, 21 (B7-B33) for B, 3 (C3-C7) for C. 21 telescopes still exist, 2 had existed until recent, other 3 are unknown. I put the corresponding numbers of 7-foot telescopes from the list of Herschel telescopes in "Dawn of Astronomy" (Seibundo-Shinkosha, 1982) by Mr Hiroshi Saida in the row "S" of this table; and from "Visit to Herschel in UK" (Hoshi-no-Techo, Autumn 1981) by Mr Seiji Kimura in the row "K".
