Description
Model of a compass sundial with a particularly decorative cutout, made of brass, unsigned but German, datable to the mid-18th century.
The dial has only one latitude, apparently for Berlin.
Furthermore, comparisons with several dials, signed by Essling or Koch in Berlin, reveal similarities in the style of the letters and the cutout of the gnomon.
The dial measures 7 cm in diameter, and the plate 7.5 x 6.5 cm.
Good condition, complete with its protective cap.
