WTB: Early 70's Momo Prototipo. And original steering wheel for a '72 2.4S

So I bought a 2.4S that had a few mods including a flat 70's Momo Prototipo steering wheel. Which I love. But it has a crack. I knew it did, so no sour grapes. I will probably get it welded and painted and keep it as it is part of the car's history.

But it means I am potentially looking for a vintage replacement with good patina because I want to keep the look (see photos), and a correct original factory steering wheel too (nice to have with the car).

Can anyone help?
