Speaking of not knowing if something opens - I bought a parlor cabinet from a person that had owned it for 35 years - they loved it as a display item, but never tired to use it. I asked for pictures of the treadle wheel to make sure it was all there, and she sent a picture through the narrow front opening. I sent back showing how to open up the side, and she replied that she had never noticed the hinges and that the panel popped open.
