Is this mortise lock missing components? Which ones and how to replace them?
I’ve been trying to find a diagram or even a photo of the same internals, but it’s very difficult to find a matching one. This is a Russell & Erwin mortise lock and there is a 100 stamped inside. It has space for two keys, and there’s a missing toggle switch or something above the latch. I know one spring is makeshift. I just don’t know what kind of springs I need to order to replace since I don’t have a similar lock to reference. Anyone have this lock or a similar one so I can see what’s supposed to be inside?
