Lost heirloom

I lost Charmed Ancient Bone Bow Stained Shadowcraft Spaulders Bloodied Arcanite Reaper. I creted lvl 1 and wanted to keep it lvl 1, but by accident I got lvl 2, so I sent those items back to my main character, deleted lvl 2 character and with same name created new one and in main character in mail box selected to send banck, so those items got back to deleted character. Is it possible to get those items back?

They might get back after a month as mail that isn't picked gets sent to sender.
