OM System OM-3 Camera grip

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 slight indent on the top of the baseplate is designed for a piece of ant-slip rubber to prevent the grip from slipping. A 2nd model is provided without the cutout for the rubber. The camera base has a built in 38mm arca plate.
