Daisy Model 57 Pistol.

I have 3/4 pkgs. of the spring loaded shells but no pistol to use them in. The back of the pkg. states "for use in a Daisy model 57 pistol. The shells are designed to hold a 6 mm plastic pellet. Much on the same idea as a shootin' shell or Johnny Eagle shell. Any help in locating one or two pistols would be greatly appreciated. Thank you ljh7667.
