Although the steering wheel looks nice, there are no real close up pics. I would be hesitant to buy it not knowing a professional or novice repaired the wheel. I would ask who did the resto and if the wheel is returnable if not happy as this is not outlined in the ad. With a $680 BIN and a $38 shipping charge, I would ask for this info.
I had a 68 steering wheel, cracked at the hub and spokes. I sent it to http://www.garyssteeringwheel.com/ for restoration and it cost me $500 for the repair and refinish. The steering wheel had 2 cracks at the hub and spoke cracks, the metal was pitted, there were 6-8 cracks in the spokes. He guaranteed the work and it is phenomenal. I have 2 black 68 wheels, one original to the car and a spare I bought with center cap for $350. Yes, the repair work was $500 and the wheel and resto cost me $850 ($170 more than the wheel on Ebay) But again, the repair was done by a professional. You could also argue that the center horn button alone with a clear acrylic center and unfaded Bird is valued at $100-$150 alone which helps justify the Ebay steering wheel cost.
It is a nice find, don't get me wrong..It's the reliability and workmanship that I would look at. If you have a core, ship it to him and you will not be disappointed. However, a novice completing this work without the proper material, periphery/supporting tools of the trade, and experience, this wheel may not be what it purports to be. Again, the lack of up close pics in detail has me concerned.
This isn't a bashing to the OP...just using my past experience in the matter.
