This 105mm M68 Tank Gun Coller is an original U.S. military-pattern component associated with the M68 105mm tank gun. Identified by Part Number 8765679 and FSN 1015-769-9843, it belongs to the parts family for the M68 gun system, the American version of the British L7 105mm rifled tank gun used on the M60 series and on the M48A5 upgrade program.
The M68 became one of the defining U.S. tank guns of the Cold War. It gave American armor a reliable 105mm main armament capable of firing a wide range of anti-armor, high-explosive, smoke, and training ammunition, and it remained a major U.S. tank weapon for decades. Because of that long service life, original M68 components are useful not only for restoration work, but also for museum collections and technical reference displays centered on U.S. armored fighting vehicles.
Based on the available public stock-number trail, P/N 8765679 appears in the M68 breech assembly/breech operating and closing mechanism section of an M48A5 repair-parts manual. In the publicly visible snippet, it is listed in the same immediate area as the firing contact plunger and firing plunger insert, which strongly suggests that this “coller” is a small breech / firing-mechanism component rather than an external mounting or tube part. I have not found an open-source public resource that cleanly expands the item name beyond the nomenclature you provided, so the exact official wording for the part itself should be treated with caution.
That said, for collectors and restorers, that kind of detail is exactly what makes a piece like this useful. Small gun components were often lost, swapped, or discarded long before major assemblies disappeared. Correctly identifying M68 parts with matching part numbers and stock numbers is valuable for:
- M60 and M48A5 tank-gun restorations
- Museum and educational displays on U.S. armored firepower
- Technical reference collections of original M68 gun components
- Spare-parts inventories supporting preserved Cold War armored vehicles
