Can anyone tell me about this steering wheel

Hello Experts

We have this steering wheel from a series 3 car we recently parted out that seems to be quite nice, (car was a 1980 Daimer)

We are trying to determine if the brand is infact MOMO and or a factory option?, it seems like this was installed from the factory? does anyone know about these?
interestingly it goes directly onto the jag without a boss kit and has a horn button extender.

Not factory, although a very few similar-ish 4-spoke leather wheels were used on JaguarSport / TWR special editions (see brochure section of old website).

Thankyou very much Peter
