Dear colleagues, The Wuerttemberg State Museum at Stuttgart holds a rather rich collection of instruments, among them many portable sundials. A scientific catalogue of the sundial collection, compiled by Juergen Hamel and Irmgard Muesch, has appeared today as vol. 63 of "Acta Historica Astronomiae": https://www.univerlag-leipzig.de/catalog/bookstore/article/1857-Die_Sonnenuhren_des_Landesmuseums_Wuerttemberg_Stuttgart
The catalogue describes 118 objects by texts in German and by photographs (one or more pictures in colour of each object). Among them are also several rare and very interesting objects. Some of the objects are also described in the digital catalogue of the museum: http://www.landesmuseum-stuttgart.de/sammlungen/digitaler-katalog/ (search for "Sonnenuhr"). However, the descriptions in the book are more extended. The printed catalogue contains also registers of the types (17 main types + 6 sub-types), of the 55 makers, of other names mentioned in the descriptions, and of the proveniences.
