This is the screw on the front of the body casting which engages the door latch. New old stock. Package of 1 shaped screw. Made by Rollei Germany. Please Note. We purchased many of the parts from Rollei of America's the closing Colorado service facility in 1985. Many parts were packaged and new. However, the majority of the TLR Rolleiflex and Rolleicord parts were loose new parts from the drawers by the tech workstations. Some of those parts have very minor marks from rubbing, sliding or touching other parts as the tech would rummage through the drawers looking for a particular part.
