I think the Mantua plan is not correct.
That you can’t see them on the 2 at the top is maybe because of the sunlight.

And also on the 5 on the main mast. And on the mizzen to the front.
An the end with the all the 15 spars, the gaff and sails it will be a impressive rigged model. I’ll keep following you rigging with great interest because I do love rigging!
The AV is still on my ‘to-build-list’.
