Yep, old skool Momo's that you could colour code the spokes on, terrible imo.
Even though Ford added them to the car as a demo type thing, they are still aftermarket and i would personally go for standard Cosworth wheels, but keep the Momo's to show as part of its history incase any pics surface of it in its original state.
Looks a nice find, wonder if it will add value with the background of it.
