"Dual Model Series" Dougram
The backpack can be detached, and has an awesome cannon which can be rotated down to a forward "firing" position.The early photos I took of this mech definitely did not do it justice. This is a great 80's toy identical to it's japan release. I also have the unapplied decal sheet (yep just like for models) and instruction booklets, unfortunately the box is long gone. This figure is mostly zinc-diecast, the removable armor and accessories are a high quality and detailed plastic. Paint apps are sparse because nice in color plastic is used throughout the figure - if I applied the decals there would be many more details added.
There is a forearm gun piece that clips in to replace the plain dark blue part - seen above on the right arm.
A great feature of this toy, aside from the removable armor and weapons, is the mini hydraulics built into the lower legs. It's just a great detail to add, which you would never see if you just left the armor on. That's what I love about Japanese toys, detail, detail, detail!
