What font did LEGO use for their 1980 trains set numbers?

In the 1980s, LEGO used a font similar to Helvetica for the set numbers on the building instructions. I've created a collage that contains all numbers from 0 to 9. Any help identifying this particular font would be much appreciated. Bonus points if a pointer is added to the corresponding font file. Thanks!

The closest I can find is Neue Haas Grotesk.

Yes, that's it. Thanks a lot!!
