How much of the Torchwood-labeled stuff was left over from London Torchwood? Like, it wouldn’t surprise me if Jack liberated equipment from there in the aftermath of Canary Wharf.

That certainly seems possible. Ianto might have pitched in, too. After all, he kept a Torchwood brand Cyberman in the basement, right?

It’s canon that Jack went to London with Owen after One fell, I’m pretty sure. I bet he took more then just Torchwood pens (but he probaby took those too). I think Ianto didn’t show up until after they got back.
