This was HUGELY helpful.

Seeing something odd. Walking down that line, 

  msg = inbox.get_item items[0].item_id

Works fine. I can see some attributes, such as:

  msg.item_id

=> "AAMkAGEzNmExNzEzLTcxMjEtNDM5YS04NmE0LWE0NWU3MWZiMjEwNgBGAAAAAAB4VZcbdHrATrbGrKL0ANCfBwCjSVkOjPEtQoJN3xOKeIYJAAzyZ5e9AACjSVkOjPEtQoJN3xOKeIYJAA25w05NAAA="

When I trace the whole object, I see that there's a node for attachments with a file_attachment inside:

  :attachments=>{
    :file_attachment=>{
			:content_type=>{:text=>"image/png"}, 
			:content_id=>{:text=>"94C552FB-8474-437C-AB44-DDF809047AB9"}, 
			:attachment_id=>{:id=>"AAMkAGEzNmExNzEzLTcxMjEtNDM5YS04NmE0LWE0NWU3MWZiMjEwNgBGAAAAAAB4VZcbdHrATrbGrKL0ANCfBwCjSVkOjPEtQoJN3xOKeIYJAAzyZ5e9AACjSVkOjPEtQoJN3xOKeIYJAA25w05NAAABEgAQAK9ad+6BP7VHru83AO7CTrU="}, 
			:name=>{:text=>"Hollowbody 2.png"}
		}
	}, 

But when I do 

  msg.attachments

=> []
