My two cents on this one...
YES, there is value in this model.
It's a super cool old model as is, and represents our C/L history, at least to someone or some of us. It is too often forgotten these days, but there is value in that itself.

Please don't go "short attention span", get greedy, and tear the engines off or dismantle it in any way just to try to make a buck or two that won't matter to anyone in a few weeks. If anything, restore it just enough to fly it once more just so you can say you did, and then hang it on the wall and admire it. If going after that risks losing the model altogether, then just hang it on the wall as is.
Either that, or give it to someone who appreciates the "value".
