An exceptionally fine very large complete adult internal mould with some patches of test. The strong, deep, mainly bifurcating ribbing shows well over 5 whorls and many sutures including the last are visible. The body chamber occupies just under a whorl, has an almost complete peristome and shows slight fading of the ribbing over the last 1/3 whorl - a feature characteristic of macroconchs. This item is cast in plaster and hollowed out producing a lightweight shell of ~10 Kg. Mounting hooks are available if specified. England, UK.
