A lot of those items look vaguely familiar. My first tank was metal framed. I had a little box filter in it and a tray that hung on it for the air pump. I don't think the tray was metal though. I remember the cardboard fish food containers too. Nice finds. (Wish I still had some of my old stuff. The only thing I have is my old sea monkey kit. )
Those are too cool. I have a metal rimmed 10g i need to reseal and set up. Thinking i might move away from the planted tanks and go art-deco with this one.
