Berkroy Sheet Metal Tools

Cross posted this on owwm, but thought I'd see if anyone here had experience with these tools. Got them from my uncle who used them to teach Ind Arts. Anyone know anything about them? They appear to be more "instructional use" than anything but I thought they might be handy for the occasional small stuff I do...IF I knew how to operate them...

Pics kinda small for me to really tell but it looks like you got a small slip roll, a hem roller or rosary shear can't tell for sure, a small brake, and a bead roller. The green thing is a scroll saw, or it looks like one.
