Paul, This is the best I could do.You might be able to scale the photo. It will be quite a job to build a replica.
Regards, Cliff

EXHIBIT #24

106-MM RECOILESS RIFLE M40A1 USA



Using Newton’s third law of motion (one action is equal to opposite reaction), the recoilless rifle fires a high-velocity perforated round which allows ignition gases to escape rearwards, while also pushing the round forward out of the barrel. So this meant that the operators still had to get out of the way when the gun fired if they wished to live long and prosper. First manufactured in 1953 to replace the smaller 57-mm model, it was also mounted on a short-legged tripod (M79) or a pillar mount on a mechanical mule (M92)
