Though it seems it's based on a Logo or the other way round:

Oh, I didn't know that.

Well, logos are often custom designed or tweaked. But I could be wrong; maybe somebody knows what this typeface is.

Thanks for your help.

Did some more research and It does seem to be a logo based on a font like Rockwell, Geometric SlabSerif or some other you've mentioned.
