A quite unusual form, which seems unrecorded, of a electric microscopical bullseye with lamp. The instrument is not signed, but certainly from UK or US. The datation is not easy but we can date it from 1910s’ or 1920s’.
A large bi-convexe lens is mounted on a sliding brass arm behing which is put a electrical lamp.
The main microscope lamp is mounted on a stand which can be rotated horizontaly and verticaly.
Very unusual design.
The lamp measures 33 cm.
