I was at a small logging museum in southern Or. and found the following equipment of interest:
A cat towed grader Machine # 2-A-277
An Adams leaning wheel #8 towed grader.
And the jewel of the junk. A Best 60 Model A Sn 1794 Eng # 4790. The museum guide stated that they would like more information on the Best and if possible some help in restoring it.
They also have a cat 2 ton and an R4 that have already been restored. I ahve picture of all of them if anyone is interested.
