A friend picked up this camera at a yard sale in Truth or Consequences, NM some years ago and gave it to me.
The No. 3-A Folding Pocket Kodak was made from about 1903 to 1915. It was pretty close to state-of-the-art with a shutter going up to 1/100 and a two-element Rapid Rectilinear lens. The camera produced a postcard-sized negative on 122 roll film. In the picture below, the 122 reel is on the left. Next to that in order is a 116 reel from my 1-A Special, a 120 reel and a 35mm cartridge.
Now, I'm pretty sure that the camera in my possession is not Jack's because the last patent number inside the back is 1909. However, it does appear to be the same or very similar to the camera London can be seen holding in a picture that appeared today in the NY Times Lens blog. The picture was snapped in 1904 while London was in the process of being arrested by Japanese military authorities for taking unauthorized pictures during the Russo-Japanese War.
While the details are a little hard to discern, you can see in a zoomed-in view that there are great similarities to my No. 3-A, including the rounded form, the two slim struts at the front which hold the lens board, and the pneumatic bulb shutter release which juts down to the left from the camera's front. There is also the possibility that London's camera is the slightly smaller No. 3 Kodak which used 118 film, based on a comparison of the camera's length to the length of London's right hand. My 3-A model is 9.5 inches long which seems to me a little more than the camera London holds.
My own No. 3-A would need a little restoration work before it could make pictures. It has a small tear in the bellows. The lens is clear and the shutter seems to work well. The 122 roll film for the No. 3-A has not been available for many decades, but adaptations for shooting still-available 120 roll film are not terribly difficult. I'm thinking maybe I should give it a try.
