A few more pics...and I can't believe I never noticed the two number 2's on the base

one is engraved one is gilded. Can that be because it was originally no 2 of a pair? I can't think why it would be gilded and engraved - one on either side of the interior of the base. Odd.
I've also added a pic of the gilding of the snakes tongue on the stem which is quite a cute touch.
The base is hollow up to the knop bit on the stem.
The edge of the rim is bevelled on both sides.
