US (I'm in Canada so assuming this is correct). I was looking for the full part number and couldn't find anything beyond LM1200, even when going to 192.168.5.1/model.json.

This post has the same firmware details of yours, and that poster says they have the LM122-111NAS

No idea if there is an update for your version.
