Father in-laws collection

[Bobmiller]

My father in-law passed away over 2 years ago and we are looking to sell his tractors. We need help putting reasonable current value on them. All ran and had been restored. Unfortunately they have sat for over 10 years. All will need a battery and some tlc to get them going again. We have 8 Moline’s ranging from late 40’s to early 50’s. 3-Z’s. 1-R, 3-U’s and 1 GB. Any help would be appreciated. Thank you.
