Looks like extra vertical support for the toggle axle pin joint at the back of the action opening when the rear toggle is rotating open and closed just to stiffen up the whole arrangement. Like two columns of extra vertical support. Also might be like the toggle lock on early models, seemed like a good idea but with the improved stronger coiled mainspring to keep the action closed longer, it was no longer necessary. "Seemed like a good idea at the time"
