Dan, you could e-mail Gerry.
I think he only has the one arm, a Graham 2.0. He states that he has three arm wands for his 2.0, already set up with different cartridges. Graham, as I'm sure you know, has interchangeable arm wands. So he is just changing arm wands on his Graham 2.0.
At least that's the way I understand him.
