Help identify my thrower

Hi all. So. Have a proton pack that I got about 6 months ago that i purchased off eBay. It was really rough and needed a lot so I stripped the pack and rebuilt it and have been using a matty wand with it at the moment.

However the pack did come with an incomplete metal? Wand. So can someone look at these pics and maybe see if they know who’s thrower this is so I can go about getting the parts to complete it? Thanks. Jim
