Hart Avenue in the 1940s

In 1940 my family lived at 3569, Hart Avenue, Detroit, Michigan. :) That section of Hart was between Mack Ave and Goethe St. I recall that Hart was bordered on the northeast by an industrial area near what was called the Bone Foundry.
Where can i find a 1940-1950 era street map of that area?
Why can't I can't find a business by that name? Perhaps i have the name wrong?
Some years ago this entire area [[Hart Avenue and several adjacent streets and cross streets) was raised to create Conner Creek Industrial Park i think. What year did that occur?

Might it have been Bohn Foundry? http://theoldmotor.com/?p=67095

I can confirm that Bohn was on Hart between Goethe and Mack. My grandfather did some work there in the years after WWII.

Thanks very much. Phonetic vs actual spelling makes a difference.

I think around 1986.

Going by names, looks like a German neighborhood back in 1940.

Also French [[probably Belgian, given location), Polish and Italian names, which all makes sense for East Side.
