My Mom's family ran a Best 60 probably back near when it was new and finally sold it to a collector in about 1992. Don't know what happened to it but it had a Paccar/Carco drawbar blade on it. Everyone seems to think they are super rare but as of Sunday I have now seen 2. This is ours back in it's working days. My grandpa was pretty good about taking pictures of his work. He logged, he farmed his whole life. This photo is late 40's or 1950s.
