No you'd win the lottery if you found a box of New Old Stock DePersia bailers.
Congratulations on your new boat, we'd like to see more photos please. She looks to be in good shape, 1967 or older. If there is a metal Serial No. plate by the coaming we can tell you her production year.
A few notes, you may know but other readers may not, the carriage bolt on the rudder releasing mechanism should go the other way, with the adjustable thumb nut on top. Easier to adjust and you don't want that protruding below the keel. This diagram is for the wooden Sailfish and Sunfish, most of the metal parts and the principles are the same.
The carriage bolt on the fiberglass Sunfish is outside of the hull in a groove molded into the transom. When parts of the rudder releasing mechanism become worn or loose, there is potential for bottom of the vertical hinge plate to pop out of the keel latch plate. Alcort/AMF began adding a nylon tube to encase the carriage bolt to reduce side to side movement of the bolt. The parts should also be replaced or tightened as needed. We have some tubing buried in our Alcort garage that may work, and The Usual Visitors in this Forum may have a good source or the original tube. Pictured below is the tube that fits the wooden Sailfish and Sunfish, and the fiberglass Super Sailfish MKII, which all have shorter transoms.
Here's the measurements for the tube:
And you can search our youtube page for tips on operation and tuning for the "old style" rudder.
