Identify old Creamery Font

I am currently digitalizing old creamery products from 1950 til 1980 in Austria.
I came along this font which labeled the entrance of the old Alpenmilchzentrale in Vienna.
Has anyone an idea?

To which font are your referring to? The blackletter one for "Alpenmilchzentrale Zentrale" or the geometric condensed sans "à-la-Erbar" used for "BURO EINGANG"?

Both.
Erbar is a good guess, the G looks similar but not the A.

I count four different fonts in that image. Compare the R's in the three non-blackletter lines of text.
