Beginner kit, all brass. Comes with a book of instructions but you still have to figure out a lot. I failed at resistance soldering, so used 0-80 and 1/72 bolts, didn't like the slot screw heads it had. I got it back ages ago when you could get an electric motor with it, no longer offered. Not easy to do, old fingers and such not good with small stuff.
