Andy: I think my information came from an old Oliver shop manual. Doug Strawser and I discussed this one time. Doug also has some information where 10 were to get a flathead Waukesha instead of the Hercules. I don'tthink any of the ones with the Waukesha were assembled in South Bend. Brady brothers over hear used to farm 5000 acres with 12 of them. They had the 6th one made in South Bend. They were there own Oliver dealer. In fact Oliver purchased a D John Deere for them to keep tract of how it compared with the rowcrops. Too bad both of them people are dead. They could tell some interesting stories on the South Bend built tractor. If you remember the story where it shows a chilled plow tractor in Paulding County  it was there tractor. This one I am talking about wer both on a farm sales in Paulding county. Keeping that Detoit running good? John
