Oh, you do? Well, lets look at the evidence.
The first image, here, is from the Wisconsin Historical Archive. The low numbered image ID (8173) shows it was listed a while ago, as in the Guy Fay era of cataloging at the archive. Also, pictures don't lie. Those are 10-20s in the picture, dated April 12, 1923. The wall full of windows & overhead crane are the same. Also, the Farmall plant in Rock Island was not built yet.
Next we have A's, B's & crawlers that are painted up for the US Army (image ID 7237). This picture was listed as taken in 1941. It shows the same overhead cranes & craneway as seen in the picture posted above, as well as the one by the original poster. The camera is pointing north. You can see the building, with the same windows, on the right & the main building of the Cook County Dept. of Corrections is off in the distance in the top left area of the photo.
The next photo is a screen grab with my cell phone. The usual GIS page for Chicago no longer has older aerial photos listed. Not going with Historic Aerials for many reasons. I didn't find any way to copy & save the enlarged image, either. The credit goes to the University of Illinois at Chicago, Chicago Aerial Photo Services, listed by the CARLI Digital Collections site. It's description is: Chicago Aerial Survey 1938 #6, Chicago Sanitary and Ship Canal, Kedzie to Hoyne. You can see, near the center of the pic, the shipping dock, craneway, the Tractor Works proper, et alia. The Dept. of Corrections is top left.
If you would like more evidence or have undeniable proof otherwise, I'll be here all day.
