As a fan of briefcase guns, this intrigues me. Thanks to my friend Erik C. who recently returned from his trip to Berlin for this photo. He shot it at the Berlin Spy Museum. There are some really interesting things going on with this briefcase design. First of all, I have never seen this briefcase gun before. Rusty and I both have briefcases for our MP5Ks. While there have been a couple other homebrew briefcase guns but I have never seen a CZ Scorpion briefcase before.
Let’s take a closer look at the CZ Scorpion briefcase. As a fan of briefcase guns, I have high standards for what I consider a good briefcase gun. The MP5K is peak performance. A good briefcase gun uses mechanical means to activate the trigger. Using string and/or electric motor/servo is lame. This CZ Scorpion briefcase gun appears to have an incorrectly positioned trigger actuator but it does appear like it could manipulate the trigger if it was positioned properly. There is even a spring to keep the trigger bar forward.
What I could not discern is how this bar is actuated. I do not see anything protruding outside of the top or sides. Could there be some convoluted mechanism that reaches to the bottom of the briefcase? Possibly just like the MAC-11 briefcase gun. But I have my doubts about that. There is no reason to position a linkage that far down. I suspect that maybe this bar bends outwards to the side of the briefcase. In its current orientation, it would be under the briefcase. While I cannot see into the briefcase as this is the only photo Erik C. took, having the trigger actuator manipulated out the side is the most direct and simplest way to do it. If that is the case, pun intended, then the shooter only has to push that bar down and it will press the trigger.
Looking at the bottom of the briefcase, it appears they store the wire stock in a lower compartment. You can see a metal plate screwed to the wood in this compartment. The compartment is for containing the brass and the metal plate is to protect the wood. Look at the divider between compartments. It has a hole for the front sight and another hole just above the ejection port of the CZ Scorpion. This is also why the gun is oriented upside down in the briefcase. Let gravity do its job and possibly reduces the chances of a malfunction. Brass bouncing around and back into the ejection port thus jamming the gun is a problem for briefcase guns.
Have you seen this briefcase before? Do you have any info on how it is actuated when the briefcase is closed?
