They were made by both Daisy and Crosman. Any BB gun model starting with 799 was a Daisy and any BB gun starting with model number 126 was a Crosman.
I can not find a CROSMAN model 350 BB gun, Do you mean a V350 BB rifle. If so then one in good condition is worth between $55-$70

I know of No Crosman BB GUN model V35C. However Crosman made a V350 BB Rifle from 1962 to 69. If this is the rifle you are asking about please post the condition of the rifle. ( excellent, good, fair or poor.) It was a push barrel rifle. Is it in working condition? Repost with the information.

The SP2022 has a better warranty. Faster FPS and cost less.
I assume that you are asking about a .177 caliber BB gun not the toy 6mm plastic BB gun. You didn't state the model of the CROSMAN BB gun. If it's still in production you can get the parts from Crosman.com If it's out of production I suggest that you look on the web under Airgun repair and find a shop close to you to do the repairs.
Crosman owns Hahn... See the link below.
Crosman offers a free service to locate shops that repair older Crosman products. See the link below.
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
