I was wondering what are these cut outs for?

Something for training? Or a display model to highlight build items?

That's where the side engines go. Or at least used to go

You mean like thrusters for quick turns?

Cool air intakes before the days of air conditioning?!?!? 🤣🤣🤣

What holes?

Those are vinyl stick ons showing you what's behind the sheet metal, of course!

[Shvegel]

I think it is a model to show you how Mercedes went the extra mile to seal all the seams and prevent rust.   Bwahahahah!

To highlight the internal structures for PR purposes?
Good stuff Pawel.

I was thinking: training purposes, testing, showroom, advertising folder...

Maybe someone who has the advertising materials from those days saw picture there with these...

In the late 40's/early 50's dealers sometimes had plastic windows in the hood of a showroom car so prospects could easily see under the hood.  The hood could be removed when the car was sold and replaced with an uncut one.  Perhaps this is an MB version of that?
