There was a movie with Brian Dennehey where he had the head of a large tri-pod modified to shoot .22 caliber bullets with a silencer, firing mechanism, and trigger assembly from different parts of camera equipment.
I think it was "Gorky Park" and I believe Lee Marvin also starred in it. If you have a large tri-pod and the TSA agent has seen the movie, he may disassemble it and search your checked luggage.
At a County courthouse checkpoint here in Milwaukee, WI, one of the security people disassembled my aluminum cane to check for a sword attached to it. Many people are not aware that you can buy an aluminum walking cane that has a sword blade attached to the bottom adjustable leg.
I'm going to have to rent that movie so I can make a pistol like that without the silencer which would require a tax stamp.
If anyone knows that it was not "Gorky Park", but another movie, please advise.
