all of Gravina's posts for you to pick through, all the reports from Q1/21 through Q4/27 are in there, along with a number of designs that never made it into the Encyclopedia.
There's a few other points I'll ship over via PM.
(Edit to original post...it turns out the 1926 AV design
was posted... exactly one year ago today. o_O)
