The two red victas and the rover would pull some great money if cleaned up . the green powertorque would be another good one provided you found a catcher that fits (heck I thikn most high arch ones from an 18" would fit)
The big tecumseh I have had a few like that, very quirky carb on them, I have never had any luck with. Worst case take the engine off the green powertorque base and bolt her on for a more "modern" looking mower!
