I have always loved the look of those old steering wheels like the ones that came on the W115 like this

I've seen W115's with the W123 style steering wheel, so I guess they made the switch sometime during the W115 production years, so maybe they are interchangeable? Anyone know? Or can anybody look at two next to each other?
