Made in Italy and has a stamped # of 50228 (see photos). 360mm in diameter, (about 14.25 inches) and is a 6 bolt. I've been informed it is a genuine walnut Nardi classic 14.3 360mm steering wheel (however, there is no E. Nardi signature on this model). Looks like it's a gem and pretty rare.

Statement from the Nardi collector/expert:  

"For this particular design, there is no E. Nardi stamp. The stamping of "made in Italy" proves it was made in Italy. The serial number at the back close to the horn button center ring is the signature of Nardi. All Nardi steering wheels would have a similar serial number."

Used, in really good condition. It's a very solid built wheel. There is a scratch at the top of the wheel and a couple slight scuffs, but nothing bad at all and not really noticeable. See all photos for condition. Will not come with the NRG short hub or the Nardi horn button (see my other items for sale), just the steering wheel. I liked it particularly because it is almost flat, it does not recess towards you like the drift steering wheels. I also liked the almost flat "T" 3 spokes in the wheel, hard to find this look. I used it in my PL521 Datsun 521 truck. It is about 14 1/4 inches in overall diameter. Thanks for looking.
