Forgive me if this is really obvious and i'm asking a dumb question but...how do i load this thing? I'm used to there being a spool on the other side with a hole to slot the film into. But that's not the case here. And being a skint student i don't really want to waste what film i have experimenting til i get it right So a heads up would be great. I've included the photo for better/easier explaining. Cheers!
