load data
Made in 1955. Release the lever on the left side, let the slide pop back. Tip the end of the barrel down. Load a pellet in the top barrel (1) or bb's in the bottom. Close the barrel. push the slide forward. Fire.
No It is not a repeater , you must re cock and and hand load a pellet after each shot!
Ask a gunsmith for help
You can load as many BB into the repeater as it will hold, BUT only one pellet at a time can be loaded into the barrel. One shot one pellet.
On the left side, release the thumb latch and let the slide jump back. grab the very nose on the front of the pistol and tip it down. Load bb's in the top chamber or load a pellet in the bottom barrel (But not both at the same time.) Close the barrel. Pull the slide all the way back and push it forward until it locks. You are now ready to shoot.
