a visit from security was shrugged off by saying it was a prop for a movie.No it wasn't made for any practical reason, was only converted to this as the brass gave it a nautical look. It did work, however the broadhead tended to act like an anchor making reeling it in problematic. Edited for content.
Its a 1" bore barrel coaxial with a 2.5" brass chamber. Coaxial piston piloted by a modified brass solenoid valve piloted by blow gun trigger.
The sight was a crosshair made from solder wire, this was done so to aim it in you would just bend it a bit until it lined up a quick easy adjustment.
Its staple diet was not the harpoon (got sick of bending that back straight), spent shotshells are a nice fit in 1" barrel so sliding them down backwards gives a nice fast straight shooting projectile. They could be modified as in the attached pic, I was driving the nails into a concrete wall and the other would pop into a cloud of whatever your loading was. Nice abundant ammo is your a keen shotgunner though you can buy bag fulls for the purposes of reloading if you wanted.
Sadly the gun come to rest in the junk pile and is in a sorry state now, see pic. I'll have to give it a polish up I think.
