Hey all. I've inherited my uncle's 8n recently. I've looked at a lot of posts here, but am still confused on determining the number of the tractor. Horizontally right behind the starter on the left side, it's got N F 200. I've read that the letter is the month, and the number is the day, but not sure how to convert this one. Right below it, it's got the following, vertically: "8N-B 1". I'm fairly sure I'm not lucky enough that this is number 1, but would like some confirmation from knowledgable folks like yourselves when you get a chance. I'm guessing that the 1 is likely the casting number if anything. There are no other numbers that I can see, nothing with starts or diamonds or anything, I've cleaned down to bare metal and still these are the only one's I'm seeing. Thanks!
