By the way, I doubt that the regular model was a great succes. It is quite rare nowadays, so considering that is was on the market for three years (1892-1895) it cannot have been much of a succes.
The 4 x 5 Bulls-Eye is even rarer. In fact, I don't know any other example. According to an article from the seventies, the Eastman House Museum had/has four examples. I could not find any photograph of it, nor a modern day description. Also I could not find any remark about it in several 1890s photo journals.
So have a look at this milestone in camera design. I made two videos, one showing the outside of the camera and one showing the internal parts. There's not much to see in that second video, but it shows the front roll design. Oh yes, it has the D-shaped red window!
Both videos can also be seen on my website, together with the pages from the 1894 promotional booklet.
