I bought one of the above with a nice wood stock and a hammer at the Brooks show this weekend. They are also available without a hammer. No particular use for it, but I've spent money a way, way more foolishly.
I have one as well, 20" barrel in 28 gauge. Figured it would work great for trail rides in the SxS on the occasional grouse and rabbit. So far it has busted a couple clays, but no feathers or fur with it yet.
