The only dumb question is the one left unasked.
The command is the very same .own that marked the item owned in the first place. Just type .own and target the owned item again, it should work. :>
Next time you could go to the Brit bank to ask if you have similar questions on your mind, I'm sure ppl will help you out. This is an in-character discussion forum, so I think your post is a bit off-topic here too, I would have posted it in to the In-Game Assistance Forum. Hopefully that helped, I can't be too sure of that since I haven't touched WoD in over half a year.
