Dashing Feathered Cap Ornamentation missing

Yesterday my bard got a new helmet. So I moved the augments from the old Loremaster Helm of Steadfast Resolve to the new Loremaster Helm of Perpetual Reverie. But there was no augment in the type 21 slot despite the old helm having the Dashing Feathered Cap grafics and even the icon - so nothing to move.
I asked customer service if they could restore the item but was told that I *never* had had the item. Yay... I love the look of the Cap, so where is it?!

Did you delete/tribute the old helm?
Can you take a picture of the item with the stats showing and the icon and post it here? You will have to use a website like imgur to host the image.

If you happened to log in an alt on the same account during that time, the item is Heirloom, so you could pass through the shared bank to the character you want it on.

I didn't delete it - otherwise Customer Support would have told me so, I guess, instead of replying I never had it.

Loremaster Helm of Steadfast Resolve is the item I was asking about. Would it be possible for you to post the picture of it here, showing the stats with the icon of the feathered cap?
