The April issue of Shooting Times has an article on page 66 in reference to the exclusive 41 Magnum flattop Blackhawk offered by Williams Shooters Supply. The revolver in the article is a 4 5/8". I've had my 6.5" Flattop 41 Maganum since 12/09. Like the one mentioned, mine came from Williams. The 6.5" guns were released first and now they have both in stock. I thought nobody else knew or cared since this article is the first time that I am aware of they have been written about. Since I have the 50th Anniversery 357 and 44 Flattops and both 44 Specials, I felt like I needed this one too. I'm waiting for a S&W M43 to arrive at Williams(soon, I hope) and then I'll get the 4 5/8" 41 with it(save on shipping). They also have a few other exclusives like the 45 Colt Blackhawk 7.5" convertible. This info may have been mentioned before I got on the forum, if so I'm late. Bob!!
