Hello everyone. I'm wondering if anyone can tell me the logic behind the hood numbers on m2 cletracs. I'm puzzled why the data plate ordnance numbers are 3 to 4 digits and the hood numbers are 6 digits ? There are a few period photos that some early cletracs that have 5 digits painted on the seat rail side . Almost all period photos have the first digit being a 9, which probably was the serial number range assigned to the type? Any ideas?
