is it one pictured in Antique Tractors Forum by Redeye from WA? I just bought a 1947 RC60 for 700 in WA that ran. It needed one new rear 9.5 x 32 and tube which is about 475 installed. Side metal will be 400 more on yours, and nose metal 250 maybe. Then miscellaneous fix up parts, new fluids, can easily add several hundred more. Maybe offer 500 to start if it runs good. Does it have rear steel rim weights, power lift under steering wheel? How are both fenders?
