Das indirekte Richten der schweren Maschinengewehre – Indirect Aiming of the heavy Machinegun. This manual explains why the scope can pivot fully around and how that is used for indirect fire. It’s not specifically written as an MGZ manual, but a lot of questions are answered about the extra capabilities the lafette mounted scopes have. This manual also gives some detail about how to set up the searching fire mechanism, how the aiming circle is used and set up, how to use the measuring triangle (the complicated aluminum double disk device with extended legs) for plotting, aiming stakes, and the deckungswinkelmesser (cover slope measurer). About 8.5″ H x 7″ W. As the manual lays open, the left page has two descriptions which are associated with the two illustrations on the right page. There are 86 illustrations. 92 pages total. Please reference “Indirect Aiming” on your order.
