letter scale with sphere poise
This letter scale with a spherical counterweight is probably from Germany. I found an image of such a letter scale in the catalog of Blikman & Sartorius from 1892. There was a choice of four different foot versions, including this wooden foot.
Previously, other scales with a spherical counterweight have been shown, see the sphere shaped poise and this 250 grams letter scale.
A scale with a comparable wooden base is this small letter scale.
Below some more images of this letter scale.
