Can you take a few shots without your hand in the way? Hard to see exactly what you have. Almost looks like a patent model.

Need more pics of all sides. Are there any letters or numbers on it? 

Looks like a press or hopper but cant tell without better pics.

I think its what they used for long exposure photos from back in the day, its used to help you stay still.
