My guess (and it is just that) is that a Port Transportation Officer has quite different duties and responsibilities from an AFB Transportation Officer, especially during wartime. I think that when the USAF was separated from the Army in 1947, the responsibility for moving war materiel and personnel went to the logistics command (and a logistics officer) while personal and household goods (and spouses) were handled by the transportation office.
Kevin:
Only slightly veering off topic, if that is the case, how did the Transportation Officer end up with all those Commandos? I've always wondered about that.
I would agree with Kevin here. When this came up on the Colt Forum several years ago, there were posts (which I cannot now find) that suggested the Port Transportation Officer was in charge of receiving durable and consumable goods from manufacturers and producers, then arranging transshipment to the Pacific centers. ....
Any way to find out who the post transportation officer was? 71 years ago, *just* possible he's still around. Might remember an unusual gun, esp if he was a shooter himself.
