I had to wait over a week for Adorama to get the unit sent from the store to their warehouse and then to me, but the wait was worth it. What I got is a slightly outdated version, but it works just great. I am posting a few photos.
This is a Manfrotto 3087 boom kit which is provided with a 3071 stand, according to the catalog. I actually got an 008 stand which is extremely similar but does not have the one adjustable leg (for levelling). The brass spigot was also provided.
The boom is a 35mm diameter tube, provided in three sections. The photo has only two of the three sections in it. The three sections are each approximately 36 inches long.
The stand is an extremely rugged stand. It is rated to hold up to 66 pounds. The connection for the boom's pivot is a 1-1/8" diameter shaft that goes into the socket which is attached to the stand's mast. This is MUCH more rugged than the typical 5/8" diameter brass fitting on most light stands. This stand also has a built-in 5/8" diameter spigot if you want to use that for mounting a light instead of the boom.
Here's the whole rig (sorry for the junky background):
Here's a closeup of the support/pivot mechanism. This allows very small adjustments if needed.
