Does this shape appear in other series?  Not exactly, but it is similar to all of the true barrel vases, especially Early Series 142 / Later Series 45.

Height:  13 - 15 cm.

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.  They often have twig-handles (common in the Early Series but otherwise rare in the Later Series) and carry the number suffix 'H'.
