We do not know for what camera type this part is.
This is an original Rollei spare part. The price is per piece.
Our technical Rollei camera parts are meant for Rollei twin-lens camera repair (such as the Rolleiflex/Rollei Magic/Rolleicord). The majority of our spare parts are unused and in very good condition. Some of them might have some discoloration, but the cameras of that time of course suffer from the same. Most of the Rollei twin-lens camera parts were from a former official Rollei repairer.
