Very helpful, Steve. Thank you for taking the time to do this. The photos bring up a few more questions...

The tabs tie to a belt? They don't look long enough to go around the waist.
About how wide is the main body?
The long triangle appears to be pieced together and a double thickness, correct?
I understand the satin loop attaching to the epaulette button. Is the small tab sewn down all around its edge to the main body? Or just on the edge closest to the long triangle?
What part goes under the epaulette and what goes over it?

I apologize for my slowness to get a handle on this.
