Yep, my folks had a TV tower identical to that back in the mid 60's. I felt those were easier to climb than a Rohn, but I certainly wouldn't tempt that fate with something that old and damaged. If it were mine, I would cut all the steps down the middle and bury the 6 sections leftover in a ground (steps facing down). By ground strapping them together in a 360deg circular pattern, you will have formed an excellent base for a ground mounted vertical.
