The cast plate is in brass.
When I look at the tank, the strap marks indicate the filler neck still goes just behind the forward tank strap. So the neck is in the same place as it would be if there was 9" before the neck. The distance between the straps on this tank is 22", so from the front of the tank, you have the first strap centered at around 5", then the neck, then at about 27" back is the second strap, followed by another 5" to the back of the tank. Looking at the photos of Ian John's new project, I believe the extra 3" of the 9" back tank is stuffed under the cab. Perhaps the 9" necked tanks are longer for more capacity? I do note that on the 15cwt trucks the tank can't go further back because the front spring hanger on the rear springs would interfere with the tank.
I have to go mail some parcels off in a few minutes, so I'll swing by the museum and measure up some of the tanks there to compare.
OK, so I went and measured up a bunch of CMPs at the museum, and they were mostly the 9" variety. I did see a 6" one on an 8cwt where the location of the neck doesn't really matter because the tank is behind the cab. I look forward to Bob's gas tank thread to see what the differences are. I do note that there are not a lot of variations on the early tanks in the early Ford parts manual (only the F15A seemed to have a different part number most of the time), but that can wait for Bob's thread.
