Up for your consideration is this vintage Oil Lamp.
Just over 13 cm with a weighted base ( you can hear it rattle inside ) Handle marked C.W.B Bristish Made.
In VG condition for age ~ still has a wick ~ wear of the blue enamel and on the inside ~ the bottom of the glass base rim has a bit of a rough edge ( marked in last photo) ~ ~ please check all photos as they form major part of description.
Not tested so unsure if it works ~ Been a display ornament only.
