A couple of you said those are wood floors. They look uneven to me. I'm guessing they are brick.
Lighting: there are a few florescent tubes along the one wall and a few task lamps. That's it. That place must be dark at night.
OTOH, there are LOTS of windows so there's plenty of natural light. It seems someone has removed the outside scenes from the windows. I wonder why they would do that?
The vises look like Leinen, or at least that style.
Beer not wine. It's Germany fercrissakes!
Engine work going on in the same shop with general assembly - no different than most of us!
Are those pinup posters (ie. pics of women) at the bottom of the pillar between the two banks of windows in the back? And on the cabinet in the corner of the room? I'm pretty sure I see *****.
They are all wearing coveralls - a factory uniform.
No one is wearing safety glasses.
There's a cord or hose laying on the floor in front of the cars. There weren't any hand held power tools back then. What about pneumatic? Or could that just be the oxy/fuel hose?
There are very few hand tools visible. There's a Harbor Freight hammer, a groove lock pliers, a couple side cutters (or similar) and some special tools on that bench in the foreground.
Those are some pretty tall oxygen tanks. Either that or Porsche employs some short workers!
