Cars of the 20s and 30s

We received a shoe box full of old snapshots and look what we found! C R Wallace on a vintage truck with a spare tire on the side and a water can on the running baordl The license plate number is 159-414. The center photo shows John Humpfrey on the left. (Isn't the middle photo reminiscent of the movie "The Postman Only Rings Twice"? The other two reminded us of the Beverly Hillbillies. Sorry Mr Wallace.)

We think the car on the left and possibly in the middle is a 1937 Studebaker Coupe Express. On the right is a 1934 Buick Sedan series 40 or 60. Car aficionados feel free to correct us. lawrencelore@gmail.com

The car inthe middle we think is a 1920 King Model H Touring car and the other two we don't know, but they are probably made circa 1930s. Can you identify them?
