No luck in the LA CDs, which is not surprising, given that a 1950 classified ad in the Times places Extruders, Inc. at 8509 Higuera in Culver City. I think the building survived: you can see the little 2-step elevation of the roof line over what was the main entrance in the modern picture as well. It is now the Willow Community School.
