She was of the same troopship class as the Marine Falcon and so would look like the photo on this link. http://www.armed-guard.com/troop13a.html
I hope you are still on this site. Just found 10 photos of the SS Panther arriving in San Francisco from Manila, Philippine Islands on October 12, 1946. Can’t figure out how to get them downloaded - site says they are too large. Let me know if you are still interested & we will figure something out.
