Transformers G1 inspired Ravage transforms from a briefcase

Some dude has built Ravage from Transformers that transforms into a huge cassette that fits nicely in a briefcase. He writes: "Ravage stretches to get out, being folded up in a real pain in the ass!!! After a stretch, his missiles and machine guns are attached. Now he needs his mission details. The back panel comes of to reveal a secret panel."
