lot vintage pool balls, incomplete set for replacements or upcycle repurpose projects

Lot of vintage pool balls, or maybe billiard balls? I'm not sure, since I've never played either! These are about 2 1/4" in diameter.

This is not a complete set, just the numbers shown, fourteen pieces in all. All show wear - fine replacements for a vintage set, or 'game parts' for upcycle projects.
