Good Morning,
Here's a bit more information that might be of some help. It seems that your Billing kit is of the original Bluenose, rather than the Bluenose II. I know the picture I sent is of the Bluenose II, but with respect to the upper shrouds, the two are the same. However, there are a number of differences between the two. Because there is so many references available online for the Bluenose II and not too many for the original, it takes some discipline to stick to the original and not be overly influenced by II.
There is a kit out there of the Bluenose II, by Artesania Latina. From what I have seen on line, in terms of build logs and practicums, it appears that it is a very inaccurate representation of the Bluenose II and as a reference point for the original, I think it is virtually useless.
I have just purchased the Model Shipways version of the original and I have faith in its accuracy. I have done a number of their kits and find their plans to be generally very accurate.
I am currently researching details etc on line for the original. Unfortunately, references are a bit hard to find and most pictures are in black and white which doesn't help. There are a number of pictures at the Nova Scotia archives (although you have to plough through a number of pages to find them) -
and there is even some rare colour footage on youtube -
However, I think your most valuable resource is likely the website of a modeler who built the Model Shipways version. He created a very comprehensive practicum and outlines the rigging very clearly. His instructions, descriptions and diagrams are excellent, although his website is very difficult to navigate. Nevertheless, it's worth the effort working through it. It appears to me that his information is very accurate -

There is also a practicum by Gene Bodnar at modelshipbuilder.com however there isn't a lot of detail about the rigging.
I apologize if much of this is already old news to you, but I'm just sharing what I have learned so far.
