Old Vintage 1940 or 1960 (i think) Camera, SX-70

I got this vintage Camera and i bought film for it but i’ve been very scared to break it and when i took a couple pictures it hasn’t worked. the tag at a vintage store said it was either 1940 or 1960 i can’t remember. I will try and make it as affordable as possible, I will change it if someone knows about this type of camera, Any reasonable Offers are accepted. Don’t forget to Follow! <3
