John,

Ken Martin's color photo of the restored tunnel Gulch Tank (linked up thread) is the most helpful, I think:





The outside bents are two posts only. The x-shaped pair of knee braces (?) attach to the inside surfaces of the outside posts.
I see three posts on the center bent. The frost box side and rear walls are flush against the inside center post and inside the two outer posts. Anyway, that's my take.

I see what you mean about a diagonal brace spanning the three center posts at Blackhawk.





I don's see any evidence of the horizontal tie rods between the front and rear pair of posts, like in Ken's detail of Tunnel Gulch.
