Two are early (1940s) 8R series. One is a 2U (1950s). All are cable blades. Two runners and one I am sure burned (Park Fire) but it is so far back on the ranch I have not gotten back to it as the road washed out from the major rain storm just after the 99% vegetation burn. What a mess. I am located in No. Calif. just up out of CHICO. PM me if interested. I am asking $8000 for the two running D8-8R dozers. I can't give a price on the 2U until I see it.
