Does anyone know what this kitchen implement is? It came with, and the glass matches other accessories of, a Hoosier Cabinet. (Genuine Hoosier brand, from 1920s.) It has about the same capacity as the spice jars, maybe 5cm diameter. The caps at both ends unscrew and both caps are open ended with an internal perforated metal filter. It seems too small to be a flour sifter, but it could be for dusting powdered sugar (somehow)
