No. O Folding Pocket Kodak (1902)

The No. O Folding Pocket Kodak is not the first FPK (because of the number O, as some people might think), but the smallest one. The number in the model name designates the size of the picture the camera takes. The No. O has a picture size of 1.625 x 2.5 inch (4,1 x 6,4 cm), the same as the Vest Pocket Kodak of a decade later.
The No. O FPK is a bit larger than the Vest Pocket Kodak, but still it is a small camera that really fits in a pocket. The dimensions are 1.375 x 3.125 x 5.625 inch (3 x 8 x 14 cm).
The camera was introduced in March 1902 and discontinued in November 1906, during which period 20,000 were made. It cost $ 6.
It truly is a snapshooters camera, with simple specifications: it has a meniscus lens and a shutter with one speed and a T (time) setting. There also is a pull out strip with three apertures. The little built in reflex finder is remarkable: it is for horizontal pictures only. There is no finder for vertical photos.
This elegant little machine can not be focused. It has the same scissor struts as the original Folding Pocket Kodak and extends automatically to the proper distance.
