I aquired an old Brooks tank and while spooling up several rolls of 120 film decided to use this tank (since I was doing all the same film and had used my other two double tanks). In the dark, I spool my last roll and try to stick the Hewes reel into the Brooks tank AND IT WOULDNT FIT. So, lucky for me, I am a darkroom hoarder who happens to be quite organized, and I quickly remember where I stashed the black plastic bags my last paper came out of. I double bag the roll (in the dark, of course) and stash it in a drawer. A little annoyed. I switched it to a tank that would fit it (a la changing bag style inside the plastic bag for darkroom paper AND in the dark) and the roll came out fine (no thanks to Brooks). SO - this tank has a ridged lip, like for a screw on lid - do they only accept Brooks sized reels or what?
