Vern Reynolds — A Plea for Linnebach
Projection 211
George
Smedberg, a representative of the Associated
Lighting Service of San Francisco, consulted
with Delford F. Brummer, technical director
of the Stanford University Theatre, to produce
this instrument — The Westlite Projector. After
a series of rigorous tests performed on the
stages of Stanford's Memorial Auditorium
using the Westlite Projector, I heartily
recommend it as a definite step forward in
Linnebach design.
