PSI: It depends on how many times you pump the forearm. But Crosman says to never pump it more than 10 times. The 760 is rated at 625 FPS with a BB and 600 FPS with a pellet.
The 760 is not designed for rodent control. It was designed for simple back yard target shooting. You may be able to kill the snake but it most likely would take several shots.
Crosman made the model 130 in two variations the first one had walnut pump and handle 1953-1954. The second version had a metal pump 1955-1970. For a time Crosman did not put serial numbers on original parts. ( I had to do some reading to find this fact out.) Yours may be one of these models. I also own an old Benjamin that has no serial number. Reference Blue book of airguns 7th edition.

Definetly the pump master. It is a multi pump gun so the fps depends on the number of pumps.
The seal on the pump plunger is bad. The seals need to be conditioned with oil, and or replaced.

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

No they are Smoothboar.
A person can make the pump easier to operate on a Crosman 760 air rifle by applying oil to the seals. This will provide lubrication and improve the overall action of the weapon.
