I am wondering how who ever it was sent to could say the checked the crank but did not measure it.

If this Crank was in a proper shop they would also put it in some V Blocks and use a Dial Indicator to find out if it is bent at all.

You can find out something if you turn the Block upside down and install the front and back upper Main Bearing; well lubed with Oil; set up a Dial Indicator on the Central Main Bearing Journal (remember there is no bearing there).

Rotate the Crankshaft slowly so it does not move back and forth and read the run-out on the Dial Indicator.

But, except for the score marks where the dirt went through the 2 Bearings I would otherwise say they could be reused.

Do they have exchange Crankshafts available in Holland?

If it only had 160k-km not even 160k-miles I doubt if it has out of roundness that would be beyond spec. And, the Bearings look like they were getting enough Oil.
I would most likely polish the Journals and reuse the Crankshaft.

The score marks on the Crank did not cause any thing bad to happen to the old Bearings.
After it is polished even less so.

I am going to stick my Neck out and say I do not see any impending disaster from reusing the Crankshaft with normal driving.

It is going to depend on how much quality you want to build into the Engine.
