MG 1 / MG 3 Lafette Optics TDv 1240/034-13 – This March 1986 dated, military issue manual is referenced in the above Lafette manual on page iii. Originally 60+ pages with a lot of wasted space and blank pages, it has been reformatted to 40 pages with all the original text and illustrations. It is not to be confused with the much smaller manual (listed below). If you have one of these fine scopes, this is the manual that explains the ranging reticle and how to care for your optics. 40 pages, paperback. Please reference “MG3 Optics (Large)” on your order.
