Its a Tessar design. Pre WW II to about 1945. Then it became the  12 in 4.5 Raptar, Coated 
of course. 
Are the cells clear ? Or has the rear element started to decement ? 
BTW the Betax And Alphax are the same "under the skin" . 
Clean the glass and shoot it.  I used one (uncoated) for years and never had a problem.
Another version of this lens the front element have a scale around it that allows you to pick 
an  amount of softness by slightly unscrewing the front element.
The specs are:
Film size 8x10, FL=12 / 305mm Available in Barrel and Betax
