Ok, had a look. The only possible function of the left lever is to detect if the bottom lock is present or not. With lock it is turned counter clockwise so that. At the moment this does not interact with anything, which is probably good. I can only imagine, that there is a part missing, probably something which can slide in the curved slot and interacts with the disk behind the slot. There is a cut in this disk, which is in the open position at the top. In the closed position this cut is partly below the horizontal part of the slot. But how this part would look and work in detail?
