Finial #38.1  is approximately 5 3/4 inches tall not including the 1 inch diameter tenon on the bottom for mounting. I can also make it with a double ended screw for mounting.   The base is 3 1/2 inches in diameter and the widest part is 3 1/2 inches in diameter. I can make it with the plain ball or with 3 rings round the ball. No returns.
