Just a little camera grip for the Nikon J5 camera. There is a hole for a tripod screw on the bottom, this should ideally be tapped with a 1/4-20 tap. The second partial hole is designed to fit a brass 1/4-20 insert. The base includes a built in falcam F38 clip and is arca compatible. I'm not sure where the initial model came from for the f38 clip, so I can't give attribution, but if it yours let me know and I will update accordingly.
