US GAS MASK FILTER IN CAN NEW

Genuine U.S. Military M11 Gas Mask Filter — Sealed in Original Canister

This is an authentic piece of Cold War-era U.S. military issue: the M11 gas mask filter, originally produced for the M9 and M9A1 protective masks and packed in its factory-sealed "spam-can" style metal container. Lot and date markings on the filter and can (LOT BS-337-8530, dated 6-14-54) confirm mid-1950s U.S. production — real Cold War surplus with unmistakable provenance.

Because the filter arrives sealed inside its original hermetic tin, the exterior of the canister presents cleanly and the filter itself is in unopened, new-old-stock condition. The tin features an integrated wire bail opener so collectors and displays can present it opened or sealed. Expect the honest patina, print variation, and hardware character consistent with a canister that has spent decades in military storage — this is authenticity, not damage.

Who This Sells To

A strong stocking item for any store serving militaria collectors, Cold War and Korean War-era reenactors, gas mask collectors, military surplus enthusiasts, and prop / costume buyers. The combination of dated markings, sealed original packaging, and U.S. issue origin makes this a display-grade piece that moves quickly with the right customer base. Also a natural add-on for shops already selling M9/M9A1 masks, ammo cans, and other period U.S. gear.
