Mine is the Model 20, which has an ƒ/3.5 lens. The Model 25 is identical but has an ƒ/2.7 lens.
I don't remember how or where I got this. Likely in a box with other things. I was thinking this is one that I'd had in high school, but that's yet another model and is MIA at the moment. No surprise here: Kodak made a ton of similar but slightly-different models over the years.
Browniecamera.nl has the user manual for this camera (along with many other Kodak products).
Retro Thing has a nice write-up about this camera. There's also a YouTube video (below).
