I would thing in either the early 20's or late teens because most American battle ships were replacing the old lattice framed look out towers with the newer and stronger tripod type. The Arizona was converted several years before being blown up in Pearl Harbor!

Your SV4 is not familiar; I've been around a few mills and machine brands. We'll insist [politely] postings on her virtues and faults.
Aware nothing is perfect, lots of machines have features ranging from great to WTF. Fact is, reactions vary with different users.

What I "know" so far,
Knee mill
Head tilts 45 in the x axis both ways, taper pin for 90 deg indexing
Called a 5x25 w 4 inch quill stroke
About 6 foot tall, will be putting on blocks, hate hunching over to work
3mt collets for quill
1.5 or 2 hp not shure which yet
Built in power feed x axis
Built in coolant
About 1300 lbs
Reputation for rigidity and accuracy
Made in w Germany perhaps in the 50's
Came with old brown n sharp vice, 1/2" collet with chuck
Belt drive up the back side for speed changes
Reputation for not enough room under the quill

From looking at the first picture, I think the room is bigger than 44’ x 40’. The column on the right is about 3 times the height of the man standing near it. The ceiling above the man standing on the left looks to be about 3 times his height. The light above him is at least equal to his height. I count 7 lights along the ceiling above the man on the right and perhaps 1 or more could be blocked from view by the beam above going across the ceiling, plus the space between them is near 2/3 of their length. I think the room is more than 3 times the length of the column wide and near twice as long.

As I said I guestimated based on a 6" head size for the horizontal run by drawing a circle around the Tool Room Mans head and arraying them up on the wall below my red line...it took 80 to fill the length 80 x .5' = 40'.

For the desks I "assumed" they were ~28" deep based on the Gerstner boxes on them and the space between about 20" as it looked narrower than the desks (quite cramped to today's standards). Count 11/12 desks x 28" = 308" + (11 x 20"=220") = 528"/12" = 44'-46'

Not discounting your light sizing and counting, one might assume they are either 6' or 8' fixtures (but could be 4')...even at 7 fixtures it would be 42' or 56' plus maybe ~2' between them would give another 12'-14', possibly making the vertical run between 54' & 70' total. It just seemed more plausible to me to work from the floor level to account for the "perspective" of the shot based on the height level of the shot (slightly above the head of the man at the D2 Mill and about equal to the top of the mill it self as there is very little perspective) and density of the machines and workers on it.

Without the lens and focal length of the camera at shooting information, it becomes a best guess at relative sizes of objects. Photo Forensics is an interesting field with a lot of variables to account for...even the scales used and Hi-zoot coordinate measurement machines have error associated with them especially with perspective shots.

Either case there are a lot of machines/equipment/people per square foot in perhaps 2k sq/ft.

Interesting pic although a bit fuzzy. I thought all of the DH-4's were built in the states and shipped to France?? The gal on the floor could use some new shoes and found the tail skid assembly an interesting design. And the shot of Kilroy in the back is telling of the shoot.

Here is a link to the DH-4 fully assembled and some history.

And a bit more on National Museum of the Airforce...with great pics of them.

Thanks Jon!
