I put this together for the head piece range finder thingy.
The arm assembly is from a "third hand" with the wing nut replaced with a Allen head screw, the area between the plates was filled in to make the molding and casting easier and stronger.
The cylinder rings where made with tape, probably liner tape (you can see where they are misaligned and where the tape ends)
It would be really easy to install a LED in it of if you are feeling dangerous a laser.
It looks like the material used on the face of the goggles is leather, looks like pig skin by the texture.
I've been looking at shoes trying to find something similar.
It looks almost like they took slippers and added the upper part and glued on the sole.
I've tried looking for the soles and treads to figure out the make but as of yet nothing has come up.
The pattern looks familiar but I can't place it.
