I believe it's the T1 though there's nothing on the label to indicate that. Wish I could have purchased it.
Funny story about that guitar: The owner, a police officer (though you wouldn't know it from his off duty demeanour), had the Thompson and a Les Paul that he wanted me to care for when he was away on long sabbaticals. When I asked him why he didn't get one of his cop friends to look after them he said he didn't trust any of them. We laughed. He was a good guy.
