Do you have any of the brass screws left? I'd be interested in a couple. I ordered a couple of the other screws from swaco.com PN: CLA-440-2 . These take a 4-40 screw and should work as an alternative for the top screw.
Thanks! It was a fun one. At the time I couldn't find any of the parts, so doing it all from scratch has made the saber one of my favorites. I actually like how almost every piece on it is slightly, or largely, inaccurate.
