Hi, I recently picked up a lot of G1 Transformers online and these pieces were in the lot. I can't really find any information on them (except for the Diaclone Blitzwing which I am really confused on as it has everything needed to make it authentic except for the "Takara Japan" stamp). The small jet has G.K. 1984 Taiwan printed under its wing. The red truck and white truck both have "MC Toy" printed underneath. The large black 4WD Jeep has "Straco" printed on its battery compartment and walks around both forward and back. Everything else I could not find identifying marks on. Any help is greatly appreciated and if I stumbled upon anything awesome, please point it out haha. Thanks again!!!
