I wouldn't be surprised if there is some corrosion or rust in the sheath protecting the emergency cable between the frame mount and the backing plate. If there is some corrosion the cable could seize and not fully release one side. Another possibility is if the wire rope has started to deteriorate and a strand or two of wire has broken. It doesn't take much to unravel before a jam.

I don't think you can easily release the cable from the actuating lever inside the assy without removing the drum but if like the later cars, possibly you could unbolt the lower end of sheath from backing plate and take the upper end out of the frame bracket. Once sheath is free it should be able to slide up the cable so you can at least examine and lubricate the section of wire rope normally covered.
