This is an estate sale treasure that I cannot find any information on via online research. It is an oak tree which tends to signify strength and resilience.
An acquaintance who is a metallurgist scanned this for composition with an XRF Metal Analyzer. See screenshot of x-ray gun screen for actual result translated below
Silver - 35%
Lead - 1%
Zinc - 17%
Copper - 39%
Nickel - 8%

Silver and Ornamental Bronze? 
Based on weight and composition, over 9 ounces of silver in this piece.

Looks delicate but it is heavy at 1lb 11oz. 
Between 9 and 10 inches tall depending on where you measure.
The chamber that would hold a candle is 2 inches in diameter.
The hammered base measures just over 4 inches at widest point.

One leaf on the tree has a stress crack  - see photo.
Looking into the candle space it appears it may have had a pricket/spike originally.

The color variation from the poured? alloy is stunning. Natural verdigris and other patina in areas that adds charm.

Definitely open to receiving insight from anyone who knows more i.e. manufactured time period, artist, etc.

Upon purchase, item will ship via priority mail with the proper amount of additional insurance added. 

Please ask any questions you might have before buying. 

Thank you for looking.
