in the big picture it is pretty RARE, but for collectable musclecars it shows up now & then
the 383 4-speed GTS is ordered from overseas:
Y09 = EXPORT &
Y14 = "SOLD" car
the most probable scenario is a US serviceman ordering the car before returning to the US
the ship to destination is stateside & all paperwork is:
Y11 = domestic publications (owners manual/warranty/etc.)
is it B7 with a blue interior?
common with Air Force or Navy
or
is it T7 with a tan interior?
common with Army or Marines
for some reason, the majority of these military ordered musclecars are,
V88 = stripe delete (maybe they had enough "stripes" in the military?)
can you share more of the broadcast sheet?
