Oh, one more thing...
In looking at the third photo of the engine bay, it looks like the breather hose has slipped off the brass nipple there by the oil filler cap. Or is that a 90 degree brass elbow?

Joe, I wonder if your pulley failed because you didn't have the right number of shims installed?
Here's install instructions from John at Aircooled.net:
To PROPERLY adjust the belt, you absolutely must start with the belt too loose, and remove 1-2 shims at a time until the correct tension is achieved. If you remove too many, you'll wind up tightening the nut until the belt is "tight enough", but the 2 pulley halfs are not squeezed together, and as the engine rotates the pulleys wear one another out. Every rotation the outer pulley moves out at the top, then in at the bottom, out at the top, until they are ruined. By doing it the 1-2 shim way, when you get the right tension the pulley halfs are tight against the shims and one another, and this movement and wear do not occur.
Great point Ron!
First off I want to thank everyone that helped on this thread, the list is long and distinguished. After futzing around I finally got a new pulley installed. I do have another being shipped from bug city (thanks Gordon) and will swap out once it arrives. Looks like I have my first item for winter work, a little fiberglass work and paint. Spinning blades of doom indeed.
Ron I do think it was a lack of shims, took off 5 and it needed 9. What is crazy is I have driven over 4k miles since May 2012.

Joe - Any shims that you remove from between the pulley halves are usually placed between the outer half and the nut. This way you always have spares and the nut is always about the same distance out on the shaft. That way you can't tighten all the way down with slack left. Doing that might allow the pulley to wobble, probably causing eventual failure.
