long backset
It's a massive copper-clad door. Those escutcheons weigh about five pounds each. The backset has a 7" extension link. The T is loose or worn out and keeps slipping out of position so it won't pull the latch open.
I went down to the parts store to see if I could get a new one. They told me it'd be a 12-to-16-week wait, and that the five-inch version of this part would start at $410, whatever that means. They couldn't even quote a price for the longer one.
The issue is that the T keeps slipping, in this next photo, toward the camera. I'm thinking to find a very good welder who can come in and weld on a bridge piece from points B1 to B2 (must zoom in to see) so that the T can't slip out of position. (This is a photo of a knob I took out of a bucket in my garage, but it's the same concept.)
Has anyone ever seen one of these?
