Funk,
Believe it or not, he's 79 and fairly up to speed on the net; never was one to sit and rust. In fact, he's still flying his own PT-26.
I'll try to get HIM on here to answer that stuff. I remember a lot of the warstories but obviously not the way he does.
I'll send him the address and see what happens.
He flew an H model from Savannah to Nadzab as one of the 345th's first group of replacements. He's talked about the 75mm some but only one squadron in the 345th flew the G/H and his wasn't it. So he never shot it in combat.
I don't ever remember him talking external bomb racks or torps.
One funny story is about the time they ran out of the 29lb parafrags. They used those to knock out airfields. American ingenuity again...they had plenty of rebar for concrete, so they wrapped multiple bands of rebar around 500 pounders and off they went.
Think they hit Hollandia with those. Worked pretty well. Rebar will go thru several airplanes before it starts to slo down

He said when the bombs went off, coconut palms fell like matchsticks!
I'll pass this on to him.
