I have this launcher, of unknown origin, and it rocks. I’m trying to clone it but I can’t seem to find any instructions/kits that match and I’m struggling to identify the pieces I would need to make a new one.

The closest match I have been able to find, especially the three aluminum claws, are from this http://txsnapper.eezway.org/waterrocketguy/solauncher.html

Any help much appreciated!
