I've got a 30" very similar to yours. Mine is a 1952 Park 30. I had the Jacobsen Library in Milwaukee copy the original owners manual for me back in 1992 when I bought the mower. I can copy my copy and send it to you if you would like? Mine still runs but I seldom use it. No sulky and at age 80 I can't keep up with it, even though I sure need the exercise. With 5+ acres to mow, I'm happier on top a zero-turn modern gizmo.
