From the research I have performed I believe the Rafal Blum listed in the student list is the same Rafal Blum whom was born on September 26, 1929. I have come to this reasoning due to the fact that the date of birth fits perfectly into the range for students who attended School #14B and also because the occupation listed for him was student. When searching for Rafal Blum two names came up in the name search database, both spelled the same. These two names had the same birth month and day but the year was one year apart. Also the addresses listed shared one, PFEFFER 14 was listed for both one had 4 after it which could stand for an apartment number. With these two similarites it could also mean that these two individuals are actually the same people and for some reason the date of birth was changed in one set of records but not in the other.
