No. 1A Pocket Kodak Aperture Values

[DMJ]

I bought a No. 1 Pocket Kodak but I'm not sure if this is the camera the manual (see link) describes. If you look at the picture in the manual, the aperture values are marked 1,2,3 & 4. Later the same manual describes the apertures with f values: f7.9, 11, 16, 22, 32 and f45 which matches the drawing of the shutter on page11.
My 1A Pocket Kodak has the 1,2,3,4 marks and the "1A Pocket Kodak" plate on the shutter. Does anyone know what f values are 1,2,3,4?

I've attached a picture which also shows a 116 to 120 adapter I designed and 3d printed.

EXCELLENT!

This is a great way to not only do panorama in an affordable manner, but demonstrate the capabilities of these old cameras. They are often a lot better than expected.

I'd be interested to see how you modified (if you did) the film rails. My modified 3A (122 to 120) still has "temporary" cardboard and painters tape film gate.

Thank you Brian. Yes, indeed a great way to shoot panoramas and the meniscus lens is very capable !
I didn't modified (yet) the film rails. This is my first time shooting this camera and I wanted to evaluate how bad light leaks were from the red window. The 120 backing paper does not cover the whole thing. So far I improved the 116 to 120 adapter so the film sits at the bottom and covers the whole window now. Didn't get any scratches from the rails ( I used Fomapan )
Now it is loaded with Bergger Pancro and I noticed that the backing paper is a bit narrower (.5 mm?) and the numbers are hard to see through the window. I shoot at 1,4,7,10,13.
