Variation in the length of the cones is considerable. For instance, the longest cone, which was found at El-Tarif, is 52.5 cm (=1 cubit). On the other hand, the shortest type of cone, to the best of my knowledge, is the one of Padiamunnebnesuttawi (Davies & Macadam # 401). For example, the one housed in the Musée Vivant Denon at Chalon-sur-Saône, France,fm has only 6cm in length (Rondot 1988a: 274). Also, Manchester Museum has two examples of the same type: the one is about 7cm (Fig. 1. Personal communication with Dr Karen Exell, curator of the Manchester Museum. 22 February 2008.) and the other, 9cm (Fig. 2. Personal communication with Dr Karen Exell, curator of the Manchester Museum. 22 February 2008.).
There is no manner of determining whether the cones became shorter or longer over the years; this is because most of the examples available are either accidentally chipped or artificially broken by both plunderers and scholars for transportation.
