Thanks Rich,
I had seen plans which showed pits in all the stalls except 1 thru 3 but was not sure that the draftsman had ommitted the details as repiticous. It is logical that they could have removed stalls 1 thru 4 which included one pit and two additional pits from the remaining stalls or even the four stalls and three from the remaining stallsvin 1945. One has to carefull about making assumptions when doing research.
