Hannah19 is very observant to notice the cheap stock strings on that racket.
However, you want to simulate play from 1975, not actually use that racket for long term play.
Most wood rackets are softer/flexier than anything made today. OK, stiffer than T-2000's.
With soft stringing, it's a out of control trampoline.
You can use soft stringing for stiff rackets, but not both.
