Good luck with your hunt, Kurt.
The earlier patterns are as rare as Tasmanian Thylacines, but I do own one and have seen photos of others; however, I have
not seen the purely khaki ones in either variation ( as a folded loop, or with the unique mounting hardware )
The "conventional" khaki epauletes, of which I have a few in my spare bits pile, would not be suitable because the 2nd style
Philippine made ones used faceted ends on proximal side ( the portion with the button hole) whereas the ones produced for
the army by domestic manufacturers to update the old colored epaulet uniforms to post 1904 specs are both rounded on that
end and shorter in length.
This link shows my branch colored 1st type with rounded end and branch coloring, as well as a photo of the 2nd type
with faceted ends. Unfortunately, the reverse side of the of the 2nd type is branch colored white for infantry making it
suitable only for infantry uniforms before the 1904 change.
