Progress update---
About the flight jacket- after much agonizing I came to the conclusion it's screwed. The paint makes it feel like a jacket made out of a box. It's ridiculous. So I decided to scrap it and put it in the loss column.
Remember how Dropship Bob thought the headset Reese wore was the same as a smartgunner headset- a Beyerdynamic headset? Well after very close scrutiny I discovered it is actually a Shure brand headset. Either an SM10A or SM12A model:
SM10A
SM12A
Really hard to see because of the stark contrast- but here is Reese's headset. What lead me to believe it is a Shure model is the 8 little "holes" on the back of the microphone (the Shure model has the same holes). Also the distinct cylindrical counter-weight on the boom arm. Now the 10A and 12As have slightly different headbands compared to the screenused piece (from what I could makeout)- so it might be an earlier model.
At any rate the Shure headset is as close a match I could find.
And now for some more success...
Looking around for another flight jacket (and having very little luck), I went into a local surplus store and asked if they had any MA-1s.
The owner said he only had a couple left as he had just ordered some more. He had two. One black, the other sage green.
I tried on the sage green one. It was a perfect fit!!!
It was used and a little beat up. The guy asked for $20 for it!
Now on Steve's advice of using an airbrush- I bought some Tamiya acrylic spraypaint in a colour I thought looked close.
It worked!!
The fabric stiffened up slightly (I would call it a little firm) but still remained flexable.
I didn't take a before picture (I was pretty excited at the good luck I was having) so here's a similar one:
(Please no jokes about the alcohol- ya'll know I don't drink

).
And here's the after:
Really
really happy with this end result!
The paint is slightly mottled allowing the green to show through in some spots (just like the screenused jacket)!
More to come!
