Can anyone tell me what this 30's car is?

Definitely a 32, 33, or 34 something.....You are missing the most valuable part...the grill radiator shell.....If he has that, it is a big plus....Also, as mentioned it is a 4 door sedan....Which hurts the value....If it was a coupe it would be worth more.....The straight 8 is a rare one though as most from the late 20's and early 30's were 4 or 6 cylinder cars....I would say in the 2000-3000 dollar range is about right....more toward the 2000 price if he has no grill/radiator or toward 3000 price if it comes with it....
