There is definitely some scrap but TONS of gold. All of those hit and miss/washing machine engine are bringing $500+++ any more, the right brands in the correct HP can bring 5k++ (I bet that 3ph Fairbanks will bring good money). Most of the tractor $750+ machines, the threshing machines are very neat and getting harder to find $1500++.
I have also notice that more and more antique road building and construction machinery showing up machinery shows. I could see those old graders powered by farmalls bring several thousand.
Man would I love to go to this sale.
