I was recently reading thru the manual on the Kodak Folding Pocket Brownie 2 and was interested to see that a significant portion of the manual was devoted to developing the film. They list two methods. The darkroom method involved pouring the solution into trays and running the film back and forth thru it while holding the strip by the ends. This strikes me as a real pain in the ass to do constantly for ten minutes or so.
The tank method looked quite similar to the modern developing tanks, except instead of a reel, the film was wound (paper and all) onto some kind of cloth strip that had rubber teeth along the edge to create a space for the film as it was wound. There was a box with cranks and clips and other various accoutrements to facilitate this spooling operation. Also, the strip couldn't be reused until it was dry, so the instructions for developing multiple rolls said you needed multiple cloth strips.
The concept of the reel seems so simple you don't think that there was time before it was invented. Does anyone know when this simple device came along to obsolete these two cumbersome and ungainly options?
BTW, the manual also states that the film can be exposed to subdued white light after developing and washing... yes, before fixing. I can only assume that the films were so slow and that there was so little undeveloped silver remaining that a small amount of light could not fog the film.

Really easy to use actually.
