The camera has a crack as shown in the pictures. The rest of the mount is excellent and it works, but the mount needs repair. From the pictures, this is a Polaroid SX-70 Land Camera Sonar OneStep, one of the most famous classic instant cameras. Its History: It was manufactured approximately between 1978 and 1981. It features the Sonar autofocus system (the large black circle on top), which was very advanced for its time. It uses SX-70 instant film, which is still manufactured today. Regarding the crack on your camera: From the second picture, it appears that the side metal arm (the brace) is broken or missing, which is what holds the camera open when unfolded. Therefore, the camera tends to close and does not stay open. This issue can be repaired by a technician specializing in Polaroid cameras or by replacing the arm with a used part. Does it have value? Yes, it has value even when broken, as camera collectors buy them. Approximately: If it works and is in good condition: between $150 and $350, and it could be more if it's excellent. If it's broken as in your case: likely between $30 and $100 depending on its condition and whether the other parts are intact. How to load film? Open the film door located at the bottom of the camera on the side. Insert the SX-70 film pack with the metal side facing inward as shown on the film pack. Close the door. The black protective sheet will eject automatically if the camera is working and the battery inside the film pack is intact. Important: The battery for this camera is not inside the camera itself, but inside the film pack. Therefore, without film, it will not work.
