Remarks
: Quick firing field gun,
with hydro-spring recoil system, single-motion wedge breech mechanism, traverse
on pivot. It was equipped with an arc sight fitted with a panoramic dial
sights and a collimateur for direct laying. Since
the line of sight was not independent, a corrector slide, interposed between
the tangent sight and the sight bracket, enabled the trajectory to be
modified, thus altering the height of burst. It
could fire also a 6.79 kg incendiary shell (7,7cm Brandschrapnellgranate), a star
shell (7,7cm Leuchtgeschoss),
and various patterns of gas shells. |
