Got an old #1 Pocket camera with the bellows but can't open it. Theres a chrome knob at the
bottom youre supposed to pull out to slide the belows but only moves about 2mm. Something
seems to be locked . even took it out of the back but won't budge. ideas?

the sliders let it open ok but cant pull lens out. Don't want to break anything. heard it takes
120 film so itching to try it. thanks
