Helvetica Neue 75 Bold  Vorgeschlagen von Heron2001 
Arial Bold  Vorgeschlagen von Heron2001 

Also not exact but close would be Arial

and I just ran this through a program - that gives so many close but no cigars from Europa Sans, Nimbus Sans Bold, Agfa's Triumvirate, State Pro - and on and on.

I can't tell you which manufacturer this is - but it seems to be strongly based on Helvetica.
