The Original Instant Camera | Polaroid SX-70 

I am about to send mine in for CLA, hope it goes well

I just found the Sx-70 land camera in a move out pile. I’m a garbage man. So it’s out of film but when I pressed the yellow release on the side and pulled cartridge out I couldn’t get the door to shut again and lock. Will I need new film in order to make it lock ? Any idea where I can get film for it ?! Thanks

What’s that violin?!
