An evolution of the M1, the M9A1 was part of the "Bazooka"/"Stovepipe" line of shoulder fired anti-tank rocket launchers. The first of its kind, the Bazooka was a massive shift in how infantry dealt with tanks and armored vehicles, and replaced the then underpowered anti-tank rifles of the inter-war era with a shaped charged rocket that could cope with the armor plating of the day. While other designs have come about, the basic principles are still in use today, and "bazooka" is still a recognized nickname for the entire class of weapon. The M9A1 was introduced in 1944 and would see America through the close of World War II. Constructed from two sections of steel tubing, the launcher is able to be broken down for storage and transport, with a flip-out optical sight for aiming and an integral magneto in lieu of an ignition battery. Both halves are marked "M9A1" near the junction point, with a wire reinforced chamber and the serial number near the breech. The "CB" prefix is associated with the Cheney-Bigelow Wire Works of Springfield, Massachusetts, a major manufacturer of the Bazooka during the war. Includes two canvas ammunition bags, three dummy rounds (one of the rounds has a few broken/absent tail fins), "The Bazooka" book by Gordon L. Rottman, spare trigger grip assembly, rocket launcher face mask and olive drab green canvas sling.

Very fine as professionally reactivated, retains 85% applied green painted finish with some light flaking. Rewelded and repaired circular sections are visible on both tube sections from a previous deactivation. The ignition system is untested, and the optics are in fine order.
