It's A Match (O-Matic)!

As I'm gradually piecing together my Wilma Deering cosplay, I'm also paying attention to her accessories.

I knew she had a small laser pistol during the episode ("Space Vampire"), and I was able to find out which one it was.

Between Wilma and Buck, a few different models of laser gun made appearances throughout the series. The one she uses in this episode against the Vorvon, was actually made from a lighter vaguely shaped like a gun; the Match-O- Matic.

A scene of Wilma trying to fend off the Vorvon with the laser pistol, and photos of some laser pistols from the show...

It's really hard to make out what her pistol looks like, but after seeing the photos of the originals below, it became obvious. The clear vinyl holster is the same, too. Except Wilma's has an ivory band at the top that matches her belt.
The barrel is replaced by a short rod of clear Lucite. This one has a little molded addition of something on the back of the upper cylinder, and a button,,,

and it lights up! This one may have been carried by a main character....

This one is a plainer version...

In the holster...

So there's that. I was lucky to have found the Match-O-Matic on Ebay for a steal at $13. Others were going for  $45 to $60.
I also happily discovered that the barrel unscrews, so I won't need to saw it off. This will definitely make the modification process easier, but I'd rather make a mold of it, cast it in resin, and modify that to my needs.
