Protect and display your WWII–Cold War U.S. mortar optics the way the Army intended with these original transport cases for the M4 mortar sight, offered in three historically correct patterns: T42, M14, and M81. All three variants were designed to carry the U.S. M4 mortar sight used on both 60mm and 81mm mortars, the standard U.S. mortar sighting device from World War II, well into the postwar era.

Available Models

T42 Case (WWII Metal Pattern)

The T42 is the wartime metal carry case that shows up with WWII-issued M4 mortar sights. It’s the right choice if you’re restoring an early 60mm or 81mm mortar set or building a 1942–1945 display where a metal optics box is appropriate. Surviving examples are documented as “M4 mortar sight in T42 metal carrying case,” confirming the pairing.

M14 Case (WWII Leather/Canvas Pattern)

The M14 is a WWII-dated carry case for the M4 sight—period examples are marked and dated 1943. This style is ideal for collectors who prefer the field-gear look over the all-metal box but still want a correct WWII container for their sight.

M81 Case (Later/Postwar Pattern)

The M81 is a later U.S. mortar-sight case made to carry the same M4 sight but from the postwar era forward (commonly seen in 1960s–1980s surplus). Choose this one if you’re building a later 81mm/60mm U.S. mortar display, Cold War training set, or motor-pool style outfit.

Why This Matters

The M4 sight is one of the most common U.S. mortar optics, but original containers are far harder to find than the sight itself. Having the correct T42, M14, or M81 case finishes the set and makes the sight displayable, transportable, and historically coherent for the period you’re building. Matching the right case to the right era keeps your restoration accurate and makes it clear whether you’re portraying WWII infantry, Korean War, or later Cold War mortar units.
