That is an interesting post. On the 80 are the spokes flat or round? I looked at a 77 Standard in the UK the other day that came from South America. it was on steel. The wheels were red. They are red in the USA. Industrial tractors have yellow wheels, Most 77 and 99% of the 88 standards over here have cast wheels. Are there Oliver part numbers cast in the wheels? We picked up a White 2-85 one time that was to be exported. We also got big wooden boxes with it that contained the parts to make it like a U. S. model. What are the serial numbers fr the three tractors?
