Sierra Vista was founded in the '40s by Reinhold Lenaberg, and later owned by his son Leonard. They're probably best known for their cookie jars, and TV lamps from the company are few and far between. While the company history isn't fully known, they apparently were located in Pasadena, California and operation from 1944 until 1951. I've also heard it said that they relocated to somewhere in Arizona after '51, but have been unable to verify the move.
