Recycling old funfair "light" guns

Hi, first of all, I'm not sure I'm posting in the right place, if I'm not I apologize, but I couldn't find any that seemed more correct.

Anyway, my grandfather passed away many years ago and among his knickknack were two handguns and two rifles that he had crafted for a funfair he worked at. (Images at the bottom)
All 4 are originally made shoot light as far as I'm aware (he passed away when I was very young, and I've never seen them in action), they look like they are meant for light at least, as they all have lenses inside the barrel.

That said they don't look functional anymore, and especially not the rifles as my little brother wanted to rebuild them for laser tag, but only got as far as taking them apart.

The thing is I have some experience with electronics (Arduino, Raspberry PI and more) and a few years of experience programming (though mainly pc programs).
I want to make something with them, but I've had them kicking around for a while now, but to be honest, I have no idea what I could do with them.
Any and all ideas are appreciated =) (except suggestions about turning them into real weapons ;) )

Regards

It was made before video games and that sort of light gun. It went (probably) to a contraption where a mouse looking object was moving around on a vertical "floor" and you had to shoot it before it reached the cheese. (I think that's what I remember seeing in the fun fair museum anyway)

does it go to a video game? the wikipedia on light guns says thats a sensor on the end.

I'd say it might be in working condition. Only what it shoots isn't visible light but infra-red light like the NES guns. You can't see it but your camera can. If you haven't destroyed the electronics, take a digital camera(you can even use the one in your cell phone) and look at the lenses while pressing the trigger. If you see a faint purple-white light, then it is working. Remember to replace the battery before trying.

You're right, the two hand guns might still work (my little brother's disassembled the two rifles a bit too much though), however there is 4 wires coming out of the gun (black, green, green and purple) and I'm not entirely sure what to connect to which end of a battery.
