Stylus for BSR ST10, ST9, SX5M, X1H, Exco ZU14, Fidelity HF31

The stylus fits into the HF31, however it's base is rectangular rather than circular, like the holding frame of HF3, this meant having to push into place with considerable force and sanding down the bottom side so it wouldn't come into contact with the record. Once this was done, the needle worked fine and produced great sound quality.
