This photo was given to me by another collector (Thanks, Mitzi!), but I have a similar
postcard as well (see photo). The tray looks as if it were modeled on the postcard
More Air Corps items
Rare lacquered wood aviation sake cup tray. The plane here has
the number 119 on its side. Anyone have any info about that
number?
Inscribed '
Air Corps 1st Regiment, Discharge Commemorative.'
Rare Air Corps tokkuri that dates
no earlier than 1931. It has the
re-named capital of Manchuria
inscribed. The Japanese re-named
it in 1931. The characters read
'Kanto-Gun [Kwantung Army]
Shinkyo (Xinjing) Air Corps, Mukai,
Victorious Return Discharge
Commemorative.'
Air Corps cup from a unit in Manchuria. Quite interesting: the
name of the Chinese city where this unit was based is inscribed
(Gongzhuling, a city in Jilin Province, Manchuria), and it is a unit
of the Kwantung Army.  The characters in the bowl read
'Kwantung Army, Victorious Return Commemorative,
Gongzhuling Air Corps Unit'.
Airplane with rotating propellers and military star. I'm not
sure if this belonged to a pilot or if the plane was just used
as a military symbol.  Inscribed: 'Discharge
Commemorative, Kondo.'
Taken from a pilot's album. This is
some sort of Air Defense flag.
Rare naval pilot cup
Note the falling petals, a symbol of
the fallen soldier
The unit is not inscribed. Only 'Commemorative' is written.
The actual flag,
original
Pilot's badge
Very rare Air Corps lacquered wood sake cup tray. The design has a fighter plane in
silver gilt, and gold gilt pilot's badge and goggles, within which is the reflection of an
airbase.
Inscribed: '5th Air Corps Regiment, Commemorative.'
Rare design. Below the bird is a pilot badge of some sort.
Inscribed 'Air Corps 4th Battalion, Discharge Commemorative, Ishigaki.'
Beautiful pale green bottle with an embossed fighter plane and windsock.
There are some kanji embossed, too. They are faint, but they can be read. They say  'Mie Air Corps Unit, Air Corps Division Commemorative.'
The only Air Corps at Mie was a Navy Air Corps training center. It was established on August 1 1942 and was bombed so heavily in February 1945
that most of the cadets were transferred to other places.
Nicely painted fighter plane design.
Inscribed: 'Air Corps 5th Regiment, Okabe.'
Rare hand-painted fighter plane design. Blue
underglaze design on the neck.
Inscribed: 'Air Corps 2nd Regiment, Discharge
Commemorative, Matsui.'
Embossed Army tank and plane. Also a painted plane.
Inscribed 'Victorious Return Commemorative, 12th Air
Corps, 1st [Division?], Mano Superior Private.'
Lacquered wood cup with a gilt fighter plane, this one being the Kawanishi H6K  
also called the Type 97 large flying boat.

Inscribed '
Kawanishi Large Flying Boat Completion Commemorative.'
Since this plane was first introduced in 1938, we can confidently date the cup to
the same year.
