Joe,
You are very lucky to have such a machine! Time to get it into the shed and at least get it functioning again if not a full restoration. I fell in love with the one at Larry Webber's Dome Valley sale - or was that a 20?????? Need to look at my photos. I thought that was a truly gorgeous piece of machinery. Maybe it was a 20? Engine on the side? Time, as you say, flies - and so the memory fades (deteriorates!).............. Yes - it must have been a 20.
At home our first combine was an MH 726 largely based on the N American 26. As a teenager I felt like a King driving this. I would like to have one but they are few and far between now and take a large amount of storage space. I have seen so many left to rot - including our old one!
