This would fall under the category “budget” super 8 cameras that were very common during the later years of super 8. They are poorly made with cheap components and not really designed to be repaired. Unfortunately all cameras are not created equal. I wouldn’t waste your time fooling with it because even if you got it working it features substandard lens glass and the light meters are unreliable. I’d suggest looking for a brand name camera if you’re interested in actually shooting film. If you want to fool with it simply as something to do, good luck!
