If you cannot locate an original,here are some ideas.
As was suggested,contact Daisy.It may be that someone there can tell you"Use a Mossberg xyz mag,but you have to file a notch...."
Or,Shotgun News and Gunlist will often have full page ads from magazine dealers.Could be those folks would know of an interchange.
A .22 mag will either be curved like a Rem bolt rifle,or slanted back like a semi-auto pistol.They are pretty much all single stack,the .22 LR cartridge inside is always the same,so some design parameters will be pretty standard.
If you were Daisy getting your toes wet making .22's,would you invest in all the tooling and R+D to make magazines? Or might you call some outfit like MegGar in the magazine business?
Would you invest in a new,one off magazine,or buy a qty of something in their lineup?
Also,sometimes gunshows have tables of odd magazines of all sorts
If you find the rotary,a fellow gave me a Daisy bolt rifle with no mag.
I wonder if I can get a Ruger or Butler creek to work with some mods.
