I actually have almost this exact same angle of this bike on my home computer and I think I have a closeup of the information card.  I’ll check tonight.  In the mean time here’s another one.  Thanks Much to Kevin for the shot who wrote in:

  Since your interested in it, I have this picture. I can’t quite read the placard on the bike but it looks to be an explanation of this particular model. I don’t remember where I found this picture, I never keep that information,as I save them for my own enjoyment. This may even be the same bike. If your friend has more info on this model I hope you can publish it sometime.
I don’t know if you remember me but I sent you a picture of a custom Yankee 500 a couple months ago. I’m always on the look out for something different- and cool. That’s why I like your blog(s) so much!
Keep up the good work and thanks for it. -Kevin.
