An update,
The seller contacted me with this message.
"Hi, thank you for the kind note. My error and my apologies. I was careless. I will ship the proper one off to you. Sorry for the delay."
Which is nice as he just put his hands up and acknowledged his error. So I hope in 10'ish days from now I will finally get the service manual I want.
I think in the future I will make sure I can easily get the supporting information and parts before taking on a project.
