(Helen) I don't know the origins of these saxophones, but the are certainly not related to the Hohner Presidents of days gone by.
These Selmer knockoffs are most likely Asian in origin, and are interesting only because they carry the name Hohner. I've had people send me emails about them, and ask questions. My answers to these questions are always the same: Sorry, I can't help you. I don't know anything about these stencil horns.
