Hello Kenny, I finally found a certificate/warrenty of one of the tractors. It's serial number is 21415. Looking on the list of serial #s it says it's a 1923 '30'. Is that right? I sure would like someone to tell me the worth of a radiator that I'll need---and where I may find one. I don't have a 28-50 but I used to know an old man around Larned with one. It was amazing--it was not restored but did not need to be. It wasn't showroom fresh but it had all it's original paint and would fire right up and run like a sewing machine. I have a 1932 sales brochure/booklet about the 18-32 rowcrop. "Power on Tiptoe" and calenders and posters. I wonder if they are valuable and should be shared with the Hart Parr community. I would like to send you email pictures or post them somhow. I could if I had you real email address ( I think). I gotta go. write me again so we could continue our visit. I want to hear about your farm. Thank you, Gary White
