Start a new thread with pics and I’ll have a looksy. Off the top of my head I have not seen a folding one tho.I just recently acquired 3 similar trikes all in rough shape. I kept the two with the fiberglass seat buckets and gave the third to my brother for doing the swap and transport for me. They all have the differentials intact, one had a factory spring front end like yours, and one has a hinge thing, I think homemade, to fold it in half somehow. Ever seen one that folds? I really dont like the idea and I'll probably cut it out so I can make it rigid because I dont trust it.
