Yes, Well done Mr. Milliman!
It has already served me well.
I was at a friend of a friends farm yesterday and there was an old half dismantled 1/2 tonner shoved into the corner. It was covered with boards and chicken poop but I already knew from a distance what it was. Mark said, "Billy do you have any idea what year that thing is?" Without a doubt I told them it was a 54-55.1. They wondered if I truly knew until I pointed out the one piece windshield and the flat bed side rails, which I had just been studying in my guide Saturday morning!
Great info to have.
