CE Johansson Tool identification?

Hello, I was hoping someone might be able to help me out. I'm looking to identify what exactly this tool set is. CE Johansson, Ford and 'Dearborn' inscribed on each piece. I've attached pictures. If anyone could help me out I'd appreciate it

 

Gauge Block holders/accessories kit.

 

Yep - micro adjustment gauge blocks for setting castings? on to set up for inspection. Should be very high precision and may have a good value

 

Dearborn is the town in Michigan, just outside of Detroit, where Ford is headquartered. There are, or were, not sure, an assembly plant & a steel mill there as well as the offices. The Rouge River runs through it. Rouge (Red) because of the iron from the mill.

 

Should add that development & design would be/have been there too. Perhaps these are part of that process? My dad was a model maker (full size models for die plates, not miniatures) for GM/Fisher Body & had an assortment of precision tools.

 

I have not seen these used in over 20 years. The industry has gone to digital measuring.

 

@Lund1942 Perhaps you need to brush up on your history of the Ford Rouge Complex - it was on 2000 acres of land along the River Rouge that was dredged & widened to allow ore freighters to enter.
