Letter from F. Wagner Schlesinger, Director of the Adler Planetarium to K.A. Bauer, Carl Zeiss, Inc.

ZPC.S3.F1.1

In the letter Schlesinger tells Bauer that the Zeiss projector is in fine condition and is being maintained by Curt Richter. States that the only additions to projector have been a gear shift for slow daily motion and a polar altitude indicator. Acknowledges that spare materials are very difficult to find but if they have horizon lights to let Schlesinger know. If not, a photo or drawing of the horizon lights might help the Adler make some.
