Figure 1-34. Cradle & Aerial Target Attachment
On the front end of the cradle frame there are lugs with semicircular cutouts into which
the studs of the barrel socket fit. On the sides of the front part of the frame there are
round holes which hold the machine bolts, which join the cradle frame with the cradle
mount. Washers and nuts are affixed to the machine bolts. On the front of the cradle
frame there is a profiled opening which holds the cradle latch when the machinegun is
set up for firing at targets in the air. On the rear of the cradle frame there are lugs with
rectangular cutouts which hold the front end of the trigger mechanism. Under the lugs
there is a latch for the lug on the trigger mechanism housing and trigger guard and for
the tooth on the support of the attachment for firing at targets in the air. The latch
consists of the lever, shaft with tooth, spring, and pin. On the rear of the cradle frame
there are round lugs for fitting the precision elevation mechanism and for attaching the
device for firing at targets in the air.
A line is stamped into the left round lug; the notch on the handle of the precision
elevation mechanism is aligned with the line. There is a semicircular rib which limits the
movement of the handle of the precision elevation mechanism.
a) Aerial Target Attachment. The attachment for firing at targets in the air (see
figure 1-34) serves to establish a stable link between the cradle frame and the
pintle of the cradle mount when the machinegun is set up for firing at targets on
the ground and to enable the machinegun to be fired at targets in the air. It
consists of the support and rest for firing at targets in the air.
The support has on its upper end a housing with which it is joined with the cradle
frame. In the middle of the support is a tooth used to fasten the machinegun
when firing at targets in the air. The lower end of the support has a smaller profile
