According to the parts listing (attached pic) the same fuel pump with angled outlet was used from 1937-1954, although that may be a replacement unit, not necessarily original equipment.
The repair kits, have a break between 51 and 52 (second pic) however, indicating that original equipment pumps were different.
I know that the fuel pump on my '51 has straight through inlet and outlet with glass bowl. I have no idea whether it's original or not, but I believe the originals had glass bowls.
I used the number stamped on it (1523089) to get a repair kit from Then and Now Automotive.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
