The large grey lensboard does not look contemporary with the lens or the small lensboard. It looks much newer, like it belongs to a postwar monorail. What is it like on the back? It looks to me like the small black board was mounted to the gray board by sandwiching it to the thing on the back, with the screws whose ends you can see. (If all else fails you can probably drill out those screw ends.)
Did you push on the two levers, or on the mystery pins? It almost looks like the pins are intended to be pushed down, pulled up, or slid sideways to free the levers.
