You have to remember that the ball mount and spring radiate also so you have to include them in your total length for a resonant antenna. Another words once you determine your proper antenna length you have to subtract the ball and spring length from it and then cut your whip. These lengths are critical if you have a functional transmiting radio that you are licensed to operate but for a static display you don't have to be exact.
