On a side note, for a more organized list of item indexes, you can use the
Team Fortress 2 Item Definition Indexes list on the AlliedModders wiki. It's sorted by type (weapon, cosmetic, item, or craft), class (if applicable), and slot (if applicable).
Edit: I just noticed that it's missing items that are only purchasable, like bundles, map stamps, and Mann Co. Crate Key... not to mention Mann Co. Crates. I may fix that this afternoon.
