If yours does't have f/stops or focus it doesn't matter, its still a great camera to shoot. On the right side at the bottom front of the silver shutter release/film advance unit should be a small tab sticking out, thats the shutter cocking button. The shutter should self cock upon winding the film to the next exposure. You dont have to set to B or L to use it, just take the shot then push the button and push the shutter release again. You should be able to do this as many times as you want.
