The firm owned a foundry that manufactured model railroading products under the "Cal-Scale" brand. Bruce Bechtold was the grandson of the Bechtold Stage Line family. He grew up living in the Denver home built by his grandparents about 1933. He was an Air Force veteran, having spent time at Castle Air Force Base, Merced, California. Because of his model railroading interest, Oscar Neubert III (27 November 1925 Fresno, California – 27 October 1991 Fresno, California), also an Air Force veteran, introduced Bruce to Anderson and Parker. Bechtold went to work as an engineer for Kemtron after his release from the military. Parker worked for Kemtron as production foreman.
