Crystal ball stand holder Swans

Vintage metal crystal ball holder with swan motif. Includes ceramic crackle glaze orb, hollow with hole at bottom, made in Portugal. I’m not sure if the ball originally came with the stand but the stand would make a great crystal ball stand! Ball is 3.5” diameter. See video for how the metal swans move, I think the screws inside have loosened but it’s still sturdy . Maybe they’re meant to move to hold different sized orbs
