My grandfather worked for Ford Motor from 1910 to 1919. He worked directly under Ed Gray, one of the designers of the Highland Park Plant along with Albert Kahn. In the old photos I found a photo that seems rather unique as I haven't seen any others like it- the craneway at Highland Park. Someone told me that the steel wheels, lower right, would date it after my grandfather worked there, but I saw a post saying steel wheels were used in the 'teens'. Any ideas?

Not sure what you mean by "steel wheels."
All wood spoke Model T wheels had steel rims.
Because that is a factory photo, it's possible that the original negative survives and resides in the Benson Ford Research Center. If it does, then a date for the photo may also be available.
Looks like a pile of clinchers from where I sit in my Archie Bunker chair.
That would be right for the teens.
I can't help with the date but, it appears to be earlier than other pics we usually see. Most interesting is how the loading balconies only have pipe railings instead of buckets like the pic below. I guess someone must have dropped a box of parts on someone's head. In the first pic above, you can see the markings for section "X" on the left and "W" on the right as well as the number floor and balcony number. The pic I posted below shows section "X" and "Y" so it may not be the same spot. Bucket X3 40 sure took a beating. I bet Henry was not happy about that.
Not a very good "indicator", however, having spent most of my adult life on the RR, I would say that those wooden boxcars with the old-fashioned staff hand brakes certainly look to be "pre-war", and just a general guess for sure, but I'd say depression years in the '30's or even '20's.
Can't tell for sure but the items do look like wire spoke wheels and that would put it about late 25 to 27.
I just enlarged the photo and was thinking they are wire wheels also.
