After the June pat date, it says April 1, '23 or 26, I think. Upper right looks like it says "HOT" and can't make out what is below. I am looking at blow up with the color reversed, might figure it out.
It might not say HOT, could be numbers, 707 or 797, still not sure what is below that. Maybe those two lines constitute a cast or mold number, or part number. I would almost say it says JOHN DEERE, but can't see it well enough to be certain.
The photo pixlates badly after 400x blow up. After another look at normal size, I don't go with JOHN DEERE.
