Yes, you could also JB weld or JB putty stick it together. it won't have the same spring strength though.
You could also cut some metal and bend it into this shape. You may have to whack at it a bit, but 1-2 mm aluminum should work?
not a bad idea, it won't be vintage but it will be your own handiwork. You could cut 1 mm aluminum with tough scissors or snips and a hacksaw would rip through it like butter!
