I want to be clear I was given this by a stranger via CL. It is stunning in person and I am honored to share it with my friends and you all. The battery is internal and I'm not sure how to access it. I get 7.5 vdc at battery connection so one is in there. With the charger connected it functions. Lights, turret, guns fire and attempts to move. I suspect the 2 large pan head screws in the bottom pic let it come apart but I'm afraid to loosen something that looses alignment.
It's just magnificent! I will retake some lower res photos to post for the 3 meg limit. How do I post something high res? Thanks all!

cool, that small black screw in the middle seems to be to open the battery compartment
