Executed by Ian Totney in 1973.
Commissioned by the Birmingham Assay Office to celebrate their 200th anniversery.
The finial is a dish shape with the gilded arms of the Assay Office.
My reference does not give it's size. I would guess it to be at least 8 inches ( 20.32 cm.) in diameter.
This piece actually serves a purpose. What was used for ?
