Army Motorcycle troops Parade tunic

A Very rare tunic, dress or Parade tunic for Motorcycle troops, these were piped in Copper Brown and this color was used only for a very short time period around 1940-41.  It then changed to Dark Yellow for recon troops.  There are only a few of these piped tunics left anymore, and the parade tunics are the rarest!  This tunic is in mint condition and was worn only a few times.
