Martin B-57B Canberra Ammunition Box Cover Assembly, P/N 272B3040519-10, FSN 1005-568-5985
The Martin B-57B Canberra Ammunition Box Cover Assembly, identified by Martin P/N 272B3040519-10 and FSN 1005-568-5985, is an original cover or lid assembly from an ammunition box in the B-57B's fixed aircraft-gun installation. It is the cover assembly only, not a complete ammunition box.
The aluminum assembly is stamped SP 272B3040519-10 and D.C.N. 2. Its part number matches the original Martin package nomenclature and identifiers.
Historical Significance
The Martin-built B-57 Canberra was the United States production version of the British Canberra jet bomber. Martin designated the B-57B as Model 272B, linking the 272B drawing prefix on this cover assembly to that specific aircraft model.
The B-57B served during the Cold War and was equipped with fixed forward-firing aircraft guns. This cover represents the ammunition-handling hardware that supported that armament installation.
Martin Model 272B Relationship
Martin's 272B model designation corresponds to the B-57B Canberra. The matching 272B prefix on the component and its original package provides a direct, model-specific connection to the aircraft.
What This Item Is and Does
This assembly served as the cover or lid for an ammunition box within the B-57B's fixed-gun installation. It formed the closure over the ammunition-box opening as part of the parent assembly.
Only the cover assembly is offered. The ammunition box and other installation hardware are not included.
