5.2 A6M3 Oil Cooler
Intake.
sub-assembly data plate s/n 3171,
manufactured September 42. The maker was Daihan
Aluminum Factory K. K. This intake probably came
from Mitsubishi A6M3 No. 3285. It could be
assumed that Daihan's 171st cooler housing could
have been on Mitsubishi's 285th A6M3 because some
of the A6M3s would have had Mitsubishi-built
cooler intakes.
interior - aotake.
the rotating vent on seen on the
A6M2 is here replaced by three horizontal
rotating vent flaps. The intake lacks a
horizontal splitter flap in vent and there is no
evidence of any attachment points for such a
flap.
the interior is still heavily
coated with oil residue, caused by a bullet hole
through the rear of the intake which would have
also penetrated the oil cooler. Similar residue
is found on the wheel well interior side of part
8.7 and both sides of the inner wheel well covers
seen in 4.4.
