Most of the pieces from this range are small. I've seen owls, little flat flanged bottles and your shape of small bottle.
It is a delightful range, the small shapes are akin to miniatures, very well made indeed, and it is not that easy to find examples.
They are not illustrated in Mark's book, so probably date to later than the period the book covers.
The script on the base is a loopy one, known as "one of the ones that looks as if it reads molina".
