Modified Hasselblad 45047 left-hand pistol grip with shutter release. Mounts to the quick release plate on the bottom of the body. Has the 3/8" thread to screw into the tripod mount. Someone has added, very neatly, an aluminum bracket on the left side of the grip. Why? we have no idea. The grip still functions as intended and maybe you will discover that the bracket gives the grip super powers.You could, of course, remove the bracket and have an inexpensive pistol grip for your camera. Come on people, let's use our imagination!
