This is the United States Army T.F. 9 2510 black and white 1957 training film for renovating ammunition. Soldiers unload boxes of ammunition from a USAX 24668 train car (:37-1:10). Ammo boxes are inspected for deterioration (1:11-1:25). A 90-millimeter projectile is shown (1:32). Renovation is done by the ordinance renovation units, shown riding in a military jeep (2:03-2:21). A job description and flow chart documents are shown (2:27-2:57). Detailed diagrams of how to set up the renovation line are shown (3:20-6:54). First to renovate is semi-fixed 105-millimeter howitzer ammunition (6:57). Unsafe cases are marked for destruction (7:09-7:50). The propellent is removed from the cartridge case (7:55-8:33). The dented case is pounded out and the propellent put back in (8:35-9:10). The process of replacing the fuse and booster includes using a fuse wrench or mechanically removing it within a shielded location using a mirror (9:11-10:42). Rusty projectiles are cleaned, repainted (10:43-11:38) and re-stenciled (11:39-11:48). Inspection involves a ring gauge and the case is chamber-gauged (11:49-12:26). Some packing materials are marked for reconditioning (12:27-12:50). Rust is removed before repainting the metal (12:51-13:13). Damaged packing boxes are repaired and re-stenciled (13:15-13:35). The round is placed in the re-stenciled fiber container, sealed with tape (13:36-14:25), and packed (14:26-14:35). Defective fuses are destroyed by demolition (14:36). To renovate fixed ammunition, the projectile is removed using a disassembling/assembly machine (14:37-16:10). The fuse is removed using a fuse wrench and the propellent poured out (16:11-16:38). Defective primers are replaced by firing the old one (16:39-17:08). The fire primer is removed from the case with a hammer and rod, and a new one inserted using a press (17:09-17:55). Rehammered, (17:56-18:17), the case is refilled with the correct weight of propellent (18:18-19:03). A crimping machine crimps cases and projectiles together, which are chamber gauged, put in a fiber container, taped, and stenciled (19:51-20:33). For 155-millimeter projectiles, the lifting plug in the nose is unscrewed and the supplementary charge lifted out, inspected, cleaned, and gauged (20:34-21:35) and then put back in and the screw threads lubricated and reassembled (21:36-22:05). A fuse well cup is removed from projectiles without supplementary charges (22:06-22:30). 155-millimeter projectiles need repair to the steel base plate, frozen nose plugs, and rotating bands (22:31-22:58). A bazooka rocket is reconditioned, including checking electrical connections on a circuit continuity tester (22:59-23:42). Rocket fins are replaced (24:00-24:28). Mortar ammunition needs the increments removed before renovating (24:29-25:16). An operational shield and remote control is used to replace a fuse on a mortar round (25:17-25:30). Damaged small arms 30 and 50 caliber ammunition is checked (25:25-26:35). Hand grenades have a barricade pit to be thrown into should accidental ignition occur (26:36-26:57). Defusing a hand grenade uses an operational shield and is then re-fused (26:58-27:27). Obsolete mine fuses are replaced by modifying the mine on a press (27:28-29:06), before it is re-crated and sealed. (20:07-29:25). Only the shipping container of pyrotechnics are inspected (29:26-29:38). The ending is a fast summary of the rest of the film.
