You are most welcome Mo.

Yes, the braces are small relative to the rectangle though - I would say 'just typical corner braces' as my recollection. I am sorry I didn't spend the time to measure more of the elements on my last visit so I could answer more specifically. The queen posts are ~6' I guess and the top chord might be more than 15' in length - maybe 20' originally given that the building is 45' wide. It is a very stout oak timber and I think the braces just prevent rack in the rectangle rather than doing much about deflection of that timber. The rebuilders added hemlock braces (timbers) tying the queen posts to the bottom chord on the outboard sides on all the trusses. We don't believe any such framing was present in the original structure.
