I am wondering what the heat gauge looks like in a 1939 truck. My 1951 Canadian GMC has nice large gauges and I can easily see where the temperature is sitting. Recently I rebuilt the motor and had the block bored and tanked. It now runs a little cooler. My 1938 Chev Master has a 216 and the temperature gauge is tiny. At the high end of the gauge the line has a small red segment. I would guess that it isn't even 1/8" in length. So it took some getting used to because when the needle moved into the red, I automatically thought that I was in trouble! I wonder if the 39 truck has a gauge like that.
