Unique Vintage Miniature Amber Glass Oil Lamp with Base

This is a beautiful miniature oil lamp measures 4 in tall it is amber glass with a metal base.  There’s a stamp on a sticker on the bottom that says peacock and something else I couldn’t quite make out.  I am assuming Peacock Japan.   It has a metal base that it screws to that is black and quite a unique piece very cute and it is functional.
