LINNEBACH PROJECTOR- HELPED DEVELOP THE WESTLITE PROJECTORVern Reynolds — A Plea for Linnebach Projection 211George

Smedberg, a representative of the Associated Lighting Service of San Francisco, consulted with Delford F. Brummer, technical directorof the Stanford University Theatre, to produce this instrument — The Westlite Projector. After a series of rigorous tests performed on thestages of Stanford's Memorial Auditorium using the Westlite Projector, I heartily recommend it as a definite step forward in Linnebach design.
