Kodak used their own film formats, 620 spools can be used to re spool 120 film.
Others can be used with 35mm laid inside the appropriate papers.
Kodak Brownie 127
Simple in operation and using 127 roll film these cameras are readily available, well documented on the web and, above all, cheap. My first costing £3.63 including postage!
When used I'll update.
