David,
Here your SA1 & A3 drawing were wrong (yours drawings show 202 meters perpendiculars => REALITY were 185 meters perpendiculars)
Only the final St Louis "gun-layout" (april 1940) have 202 meters perpendiculars
On my computer I found ...
your 2 versions
(185 meters & 202 meters... for SA1 & A3)
Sign that you confuse the 2 preliminary studies and the final design
(Having both versions,
including the good one, it seems to me that I had already alerted you!)
Be serious please
Don't forget that SA1 & A3 were 1939 preliminary design, the "gun-layout" is the final april 1940 design
Edit :
PS 1) : & now your final St-Louis "gun layout" seem even much more wrong (you add additionnal lenght ?
)
PS 2) : even all the 37mm directors disapeared !
