Greg, I'd grabbed the auction image for this photo and the info that went with it indicated the '48th Repair Squadron'.
Take a look here:
http://www.cbi-history.com/part_xix_b.htmlIf you do a CTRL+F search for '48th' on that page, you'll get a few hits including the 48th Depot Repair Squadron, which was part of the 83rd Air Depot Group and stationed at the Bengal Air Depot.
That doesn't ID the airframe, and it doesn't tell you which outfit the ship flew with. All it suggests is that this C-46 passed through the Bengal Air Depot... but it's a start.
I'm afraid that I'm lacking in resources regarding transport outfits and can't take it much further, if any. But someone who has more with which to work could hopefully take it forward...
Fade to Black...
