Hi Guys,
I have been building and flying planes for many years, and know NOTHING about tanks. Picked this one up at a yard sale. Can anyone tell me the mfg? I couldn't find anything inside or outside the model to help...thanks!

First one didn't take, I'll try again...

Sorry, for some reason I can't get the innards pic to upload, but found a newer version 0f the Tamiya King Tiger on ebay that matches pretty close, thanks

Judging by the large spring antenna in the back, I'm guessing it may be one of the 1st gen units w/ the clutch system. Does the barrel elevate via the radio or can you move it by hand? Does it have one motor to power the tracks or two? Is there a black plastic box hooked up to a servo?
I ask because there have been a few revisions to this kit made by tamiya and the older 1st gen units have not been in production for many years. Either way nice find.

The barrel moves by hand. One motor powers 2 large gears, and yes, a servo is connected to a long arm on what looks like a plastic gearbox. Any idea what this might be worth? Thanks!
