Watering Cans in the later 16th or early 17th century

Dr Ann Ryan, retired lecturer from the University of Wales Swansea and keen gardener, says:

On a recent visit to the Somerset church of Stoke St Gregory, I was intrigued by the carving on a screen, which seems to be a representation of a woman, two sunflowers and a curiously angular watering can. My guesses as to an early Jacobean date have been confirmed by Dr Dunning (Editor, Victoria History of Somerset 1967-2005) and he gave the further information that the screen had until the early 1960s been part of a cupboard, and thus was of secular origin.

Is this known to be the form of watering cans in the later 16th or early 17th century, and are there any other known examples of a carving like this?
