Deere tried to bury all mention of those and have the Waterloo Boy be the first tractor. Even with the 100th anniversary of tractor production this year they skip the Dain. The Dain doesn't fit the narrative they want to portray as their first tractor as it was expensive, complicated, and basically a failure.
Really only recently that JD even officially acknowledged them. Cool machine though. I've seen the one they have in Moline.
