Advertise it both ways. So much each or so much for all. Make it a good deal and they will all go !
Many many years ago Dad and I bought a group of I think 7 or 8 tractors from a guy. He gave us a price we couldn't refuse. Dad used a line of credit loan and we bought them all. Resold all of them except one. My cousin has it. It is a Huber grandpa had bought new. Sold the rest and oddly enough since this is the allis forum the last one to sell was the WC allis. Thought I'd never get rid of it. LOL
