The "614" is a full-bent, plump-bowled jaw-hanger Billiard sporting a design distinct from the usual Oom Paul. Each briar of the Tortuga series sports not only a tortoiseshell-patterned stem, but also a domed, shell-like cap with a foam-rubber stopper. The purpose of the latter is to preserve an unfinished smoke which one wishes to pick up again and finish later.
