Presumably the number was re-allocated to the fan vase some time after the bookends ceased production. For the kangaroo bookends identification of the incised number is less than 100% certain.
It can be seen that these bookends comprise two half-kangaroos. Both pictures show the same pair, the sole example so far recorded. A similar treatment of koala bookends appears as Early Series 337.

341(Early Series) Fan vase, wavy lip, with foot.
Does this shape appear in other series? No - (none recorded in image database).
There is some confusion in sizes and suffixes.
The foot may be round, or cut straight-sided or diamond-shaped.
Decorated versions of this same shape are recorded signed by Una Deerbon, and by John Castle-Harris, both of whom are known to have frequented Premier Pottery. Some of theirs were apparently glazed at Premier, some not.
