The hood louvers signify that this is a 1919 Buick Model H-46 Coupe instead of a 1918 Model E-46. The "H" models were introduced in August of 1918, and with them all new Buick models now had 6 cylinder engines. Buick made 2,971 of the 3,100 pound car. Sources differ on price, but according to one company brochure it cost at least $1,985 f.o.b. Flint, Michigan, where the Buick factory was located.

Shown below is the interior of the coupe which could seat four. In addition to the individual driver's seat, the passenger seat could seat two. The fourth person would have to sit on the jump seat that collapsed into the cowl, and he would have faced backwards and blocked the driver's view. Behind the driver was a tool box, and the space could also be used to store parcels in addition to the trunk on this model. The interior was in a soft gray cloth.

Although only a portion of the license plate is visible the only Buick dealer in California with a dealer number beginning with the number "5" was Howard Automobile Company at California and Van Ness Streets in San Francisco. The "R" indicates an additional plate issued to the firm. The owner of the firm, Charles S. Howard, Sr., (1877 - 1950) later bought and raced the horse Seabiscuit. His Howard Automobile Company was the Pacific Coast distributor for Buick automobiles. Two of his advertisements from city directories (1925 and 1930) are below.
