Thanks for the response. I verified it is indeed a 586-2. I found another sold thru Collector Firearms. It was described same as this one.

That one sold for 1295 but had the case. It is identical to the one I'm looking at.

Now I really don't know what the fageezy it is. The serial prefix is BAD++++. Ironic I guess. The engraving(?) looks the same as what is on my Mountain Guns.
