The Brownie's, Bullseyes, Kodets, and Cartridge Kodaks follow different numbering schemes.
Some of the early 120 Kodaks used the #2 designation.

122 and 116/616 are the two sizes I wish someone would produce at a reasonable price ($10 - $15)
It would be AWESOME if someone could start spooling #122 film again. The first difficulty is spools; the second is finding someone willing to slit the right width of stock; the third is getting backing paper printed with frame numbers. And then, of course, there is assembly. :-)
