Okay, now I have a whole new question. I was looking through a booklet that I found in my collection, and I guess that I was wrong about my model. Correct me if I'm wrong, but I thought that I had a 3/4 ton express truck because it had single rear tires. However according to this booklet, it is a 1 1/2 ton, model K30. The booklet lists it as a KH30, but according to Eric Bannerman's book, the KH30 is a 1935 and my serial number coincides with a 1934 K30. Am I correct in assuming this?
