CAN YOU IDENTIFY THIS PERSON ?

Betsy helped her dad scan this photo and she emailed it to me. I thought it was Ted at first and a Well Drilling Rig, but Charlie told me he thought it was a John Hofstetter and also that this was not a Well Drilling Rig but some Farm Equiptment used back then.
I don't remember a John Hofstetter.
Do you and can you add a story about him?
