You have to swing the forearm to pump up an air cylinder in the rifle. Usually it take about 8 pumps. When you pull the trigger it releases the air an propels the BB or Pellet.

Crosman did not make BB guns until 1947, so there is no 1924 model BB pistol. Crosman did make their first BB rifle called the 1923 model. It had a plunger under the barrel to pump up the gun. Benjamin had been using this design on their pistols starting in 1935 but crosman never used it on a pistol only on the first model. Now back to the Crosman rifles, the second Crosman rifle was the 1924 model and it used a pump handle under the barrel to pump up the gun. Yes I have a photo of a Crosman 1924 model but "Answers" has no way of displaying photos, so sorry your out of luck. FYI: Crosman is spelled with one "s" not two. CROSMAN
