my new lot of RAAF wings and bits

[badgecollector]

hi all
picked this lot up last night.
can i ask what period you think the wings are?
the bullion look to be queens crown? so assuming post 1953
i also think the 36 patch is the 36 transport squadron which was part of 91 Wing RAAF in Korea
so maybe the wings are post WW2?
of the cloth wings, the top and bottom wings are padded
the blue patch is silk and probably Japanese made. what is this patch anyway?
looking forward to your replies
bc
