I Think I Made A Booboo..

As a bunch of you may know, I finished my mythic requirements and even had to do nyzul isle, NQ, to get the weapon I wanted... issue is.. when I tried to trade said weapon, I only had the otion saying:

OH MY GOD THERE ARE NO TAKE-BACKS IF YOU FUCK THIS UP THE WORLD IS OVER! ..iterated something of that nature.

Issue is... I forgot what weapon I traded all those years ago. Is there no way to check without losing my Wyrmseeker, journals, eyepatch, sanity?
