This is one of a small group of 500 numbers that are not part of the 500 Series but instead are associated with the Later Series. In a Later Series shape book numbers 500-506 are interposed between Later Series 165 and 166. The reason for this group of anomalous numbers is unknown. Most recorded examples have twig-handles (common in the Early Series but rare in the Later Series) and carry the number suffix 'H'.
