It looks like an old BGE to me. I had a mini that had the same type of handle and scissor hinge. It's hard to tell, but it looks like a small BGE, which doesn't hold much and the charcoal is too close to the food, so your cooking options are somewhat limited. I wouldn't go over $50 for it. Although it's missing the vent cap, you can get creative and fabricate a cap or find something to use as a cap. Good luck.
