Actually, the guitar had been what he'd been thinking of, since it's more fresh in his memory given all of John's picking around on it of late. He supposes they did give him the gun back as well, though. He'd like to point out that yes, see John? They gave you these things in reward for your bravery with the caravan when Ianto himself hid under the carriage and he hadn't gotten a thing in return for that but he lets it go. Knowing that he could argue fault until he's blue in the face but that the other man will still blame himself for what happened.

"Maybe someday they will take pity on me and give me back my espresso machine," Ianto replies, helpfully. See, John? He can take a hint. For the moment, anyway. "Especially since they've frozen the rest of our things, it's he least they could do."
