Here's a pic of our 1939 F20 with cultivators. It still got it's original rubber on the back and has the factory high speed 4th gear. From what we've been told and as it appears the cultivators have been on the tractor since it was new and have never been off:)
We bought it at a local auction last summer and plan to take it to a couple shows this summer. It's as original as it gets and we plan to leave it this way
