92 & 92B (Later Series) Cream jug & sugar basin.
Do these shapes appear in other series? No - (none in image database).
In the Early Series a 'B' suffix usually denoted the presence of koala decoration. Here however we have an unusual (unique?) case of a 'B' suffix in the Later Series. No koala though - presumably the purpose was simply to differentiate the sugar basin from the jug.
