Factorio Forums

I've been unsuccessfully trying to find all the old icons for the items in the game via google image. I've been playing since 2017 and I remember many of the icons looking way different, and I think some of them have gone through multiple iterations of appearance.
There are some old pictures here and there that show how some of these icons look, but I'm wondering if anyone knew where I could find a comprehensive list of how all the icons used to look.

Simply download an old version of the game.

The Iconography Mod (ver 0.18) by Optera has some of the old icons.
It also has the old Icon of the Copper Top battery.
Just change the factorio_version to 1.1 in info.json to get it work.
You can also add icons to this mod from the older games as Loewchen mentioned above.
