thoughts on a few colour patches

[badgecollector]

hi all
what are your thoughts on these 4 colour patches?

in the first 2 pics what is the patch on the left and its produced on an unusual material? is the patch on the right a miniature 16th btn ww1?

in the next 2 pics, im not sure on the construction and the material used. is the top patch 474 (glyde), 1st aust independent LH sqd? what do you think about the stitching?

as usual thanks in advance
bc
