I don't think Arthur Chevrolet could have patented the OHV engine in 1928. It had already been in use by, many manufacturers, for almost 20 years by then. Arthur Chevrolet never had any connection to Chevrolet Motor Company or General Motors.
The truck in the photos, above, is a 1933. The grille shell is a painted version of the 1932 passenger grille, which was plated. If someone can enlarge the Id plate enough, you will find the letters CB as part of the number.
