Sorry, but I don't have a sailing date to match either of the dates you list.
As I told Beth, the shipping lists are far from complete in any respect. It is my impression that they were organized and maintained by one individual, who came down sick and has been unable to make any new input for well over a year now.
For academic purposes, try: (I think I got it on GOOGLE) which will bring up the lists for the years 1942/46.
He may have upgraded since I last checked.
The H D after ORD would stand for Heavy Maintenance.
