The ultimate development of the fighter formula initiated
by the Dewoitine D 1 was the D 25 tandem two-seat
day and night fighter also suitable for diurnal reconnaissance
tasks. Developed in response to the 1925
C2 (two-seat fighter) programme, the D 25 was based
on the single-seat D 21 with local reinforcement of the
aft fuselage to permit installation of an open turret for a
gunner. Powered by a 450hp Lorraine-Dietrich 12Eb
water-cooled W-type engine, the D 25 entered flight
test in 1926, but the C2 programme for which it was intended
was abandoned and the type was offered for export.
Four were ordered by Argentina in 1928, and
these, fitted with an armament of two 7.9mm synchronised
Madsen guns and two similar weapons on a
ring mount in the rear cockpit, were built under subcontract
by the Hanriot company (which also built the
last 10 D 21 single-seaters for Turkey).

I am interesting by this engine because was used by IAR 14 , one romanian aircraft , and I have only two view of this engine (lateral and frontal).
