This was is the steering wheel I've been using for the last 9 years. I bought this on Ebay, in 2003 for $50. It is from a special edition Saab 900, made by Momo, from 1983. I've seen one other person with this wheel in my life, and it was in a magazine.
It has lasted me for quite some time. The steering wheel is almost as old as I am! Anyhow the leather was getting really torn, and wasn't really working too well with my gloves. I began to search for a replacement.
I started searching on Craigslist, and found this. Its a 5Zigen N1R. It is supposed to be a pretty rare piece. The kid I bought it from wasn't too knowledgeable and probably wanted to get rid of it because he bought a Chinese copy Nardi. Anyhow, I bought it for $50. It was worth driving far and speaking with him (he wasn't very pleasant) just to score this deal! Anyhow I felt good about putting this wheel on my car, since its pretty vintage in itself. It is stamped "1993".
