@PK1, your emails are bouncing.
Peter contacted me about this design that i did in 2006 (Scott’s alignment).
The original sletch from the late ’70s was for the B139, modern modeling showed it was almost right on for the Jordan JX150, and when Scott came up with the alignment i drew up some potential ideas. I don’t know if the TTL has been built, but i have been contacted a few times before. Other versions of the same alignment have been built and were reported to perform well.
I’d really like to see one of these done.
I have updated that drawing (cosmetics and comments only), and i did do a sketch for driver placement for another chap. I have enclosed the updated drawing.
I have given bracing much thot, still not quite sure how to best execute. Bracing the driver and baffle against at least the inner partition i would consider minimal. The angled partition braces all the other panels but the top.

I'll try to dig out the original modeled data if I still have it -if not, I'll re-run, or potentially rework with some revisions that may be worth including into the load.
