Comparison of short frame and long frame.
My BA - Feb. ‘65 shorty S/D.
Your HA - Aug. ‘65 long frame S/D.
Several differences on these frames, but the top tube on the shorty has a more noticeable arch.
The long frame has a flatter top tube.
Another Schwinn change was the paint.
Two different Violet colors were used in ‘65.
The BA is an Opal Violet.
Your HA is called Violet which has a darker shade.
