5. Differences Between Models
a. Major Differences.
The major differences between aiming post
lights M14, M41, and M43 are in the components that make up their
optical systems and in the case constructions with their particular
bracket arrangements.
b. Differences Between Cases.
Cases differ in their clamp arrange-
ments which are constructed to fit the aiming post used in conjunction
with the specific aiming post light.
The various cases and their clamps
are illustrated in figure 7.
Another difference between cases is that
aiming post lights M14 and M43 have their clamp at the center of the
case and are closed at each end by a cover and cap.
The clamp of
aiming post light M41 is formed by one open end of the case.
c. Differences in Reflector Assemblies.
Reflector assemblies are
similar
in
construction
and
appearance.
The only difference between
them is the manufacturing specification of the finish and polishing of
the reflector of early manufacture.
Reflector assemblies for aiming
post lights M14, M41, and are identical and interchangeable. The
finish in the reflector assembly (fig. 5) for M41 of early manufacture
is
a
dull unpolished aluminum.
Component parts of the optical sys-
tems of aiming post lights M14, M41, and M43 are shown in figures
4, 5, and 6.
