You certainly have a good collection of “golden oldies”. The only vintage piece of farm equipment I have is one of the first self propelled grain headers. It’s a “Sunshine “, built here in Aus, it has a Wisconsin petrol motor to power it, steel wheels etc. It’s unfortunately sitting out in the weather and has deteriorated very badly over the years. I once thought it might have been a retirement project, but it’s probably too far gone, and I’m feeling too far gone myself these days. I’ll just have a amuse myself watching your restorations and forget about it. Regards from Down Under.
