Not being brought up in the church, I have had to consult, but hubby says it is called a cruet, which seems to be correct. It is quite beautifully detailed, and if it doesn't sell, will go into my antique shop. It comes with a little chalice, and I'm sure there is a small chapel somewhere in need of such an item. It is 4.3 cm high.
Please contact me if it is of interest for postage cost.
