Since I've started a project to start making the "sources" section of equipment pages more consistent, there is one issue having to do with that that needs some data gathering: Equipment drops from treasure boxes!
Definitely we do not want information from during the Preview.
If folks just want to post in the thread equipment drops that they have seen (either provide a date that you saw it dropped or be really really sure that it happened since public opening of the game). I'll see if I can make a page listing all equipment so you could just directly edit the data there.
Also useful could be the depth/tier you were on. If the equipment drop was from the treasure room at the end of a danger room, please note that as well because I'd like to see if those differ from the normal rooms.
Also of interest would be the strata type or specific level name where the treasure box was found. There was some speculation about equipment drop and location type, but there is probably nothing to it. Here was my contribution on 4/27/11 both from T2:

Last night someone got a Brute Jelly Mail during a Jelly King run. It was in the treasure room in Red Carpet Runaround where you need the fourth key to open the gate on the left.
I got a Spiral Demo Helm in a T2 Scarlet Fortress. Our party had three bombers in full bomber gear with 1-3 bombs each.

Summary for convenience:
T2 - Depth 16 - Jelly Palace - Brute Jelly Mail 3* from treasure box (4th key gate)
T2 - Depth ? - Scarlet Fortress - Spiral Demo Helm 2* from treasure box
