On the 1950, I believe the power cord stores inside the cabinets next to the refer, below the big closet. Try to remove the drawer right there and see if you can see the power cord. If you can, this would be a perfect place to bring in your cord. If that won't work, try coming in the refer panel. I don't know if you could get access to the inside, but it might we worth a shot.
