hammered metal teapot

Hello, I have had this hammered metal teapot for some time now, but have had trouble identifying it! One of those ongoing projects! It appears to be gilt metal with a figural solid brass spout, handle and finial; there is a mark on the underside the lid in the form of a leaf or feather, which is the key to identification! (see photos!). Can anyone identify this mark or attribute this teapot to a particular artisan or company? Any assistance with this query would be greatly appreciated! Thank you! David.

Might be Oriental; the handle looks like a stylised dragon. There are parallel lines under the hammering which is an indication it was spun first to get it into shape, probably on a machine, so the hammering is for decorative effect; the apparently chased decoration on the spout looks cast; it's still a bit rough. The finial is a Victorian shape but the lack of much patination may indicate it's post war albeit a pre-war style.
