156  (Early Series)   Slender conical carafe with flaring rim and formed spout.

Does this shape appear in other series?   No - (none recorded in image database). A jug version is recorded, un-numbered.

Only one numbered example is recorded but its use of the inch suffix '9' implies the existence of other sizes. A smaller size is indeed known but no example is recorded with a number incised.
