Genuine Rollei step screw for the Rollei 35 SE and TE compact 35mm film camera.  This is Rollei part # 19579.00.1. This is the screw on the front of the camera and screws into lens lock release lever.  New old stock. Sold as pictured. Package of 1 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, Rolleicord, and Rollei 35  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.
