Dancing Fox, Welcome to the site from a fellow Ohioan. As far as I ever found out they were all called Blackhawk whether they were built by OCC or NFM. The brochure mentioned earlier in the thread can be found here http://gardentractor...ckhawk-tractor/ I think mine are orange and black like the brochure. With 3 different models offered, some minor changes would be found. I'd say date of production could be found by some of the changes. A lot of times with this older stuff, the real challenge is to find 2 alike! Being from the Bellevue area, it will be interesting to see what you can turn up. Please sharoure y info on the forum so we can document these brands!
