Geometric Model Stand by L. Brill for Model of an Optical Surface, D41,6


This is one of a group of hollow wooden stands, painted black, which are designed to hold models like those produced by Ludwig Brill and Martin Schilling. It is a circular ring.

A paper tag on the stand reads: D41,6. A pencil mark on the bottom reads: X.1 (/) 7. Ludwig Brill’s model No. 159, Ser. 10.1 No. 7 is a plaster model for a wave surfaces for refraction in a uniaxial crystal. An example of this model is 1982.0795.21. A tag on that model reads: D41,6. It was made by L. Brill. This same model had number 357, Ser. 10, No. 7 in Schilling’s catalog.

Compare stand MA.394722.23.09, which has the same shape but no tags and a different mark.
