It is indeed not a doublet, as I mistakenly referred to. I have, and have had, several examples of this type of garment over the years.
I find that when insignia is missing, the underlying cloth is invariably lighter as these old garments most always tend to darken a bit with age soiling. I have never seen one that exhibited sun fading, but scarlet super fine or Melton does change shade to some degree depending upon how it was stored over the years.
A good brushing and wipe down with a damp towel often restores them quite well.
My regular OR's RSF doublet for reference.
