Very beautiful detective varnished mahogany wood assembled by very fine dovetails.
Operation: The plates are stored flat in stack of 12 in the rear compartment. A half turn of the crank takes a new plate under the pile to pull it by a small cart in the front compartment. A turn of the butterfly handle and plate is presented in front of the lens. The plate once exposed, another turn of the throttle grip and the plate is flipped over and placed at the top of the front compartment. The next half turn of the crank pushes the new plate forward while the exposed one reaches the rear compartment from the top of the stack. A counter on the left rear of the case shows the number of exposed plates.
