Locking and poping open should be 2 different functions and I have had both fail.
The spring for key operated dead bolt broke and I made a new one from a hack saw blade. A simple fix.
The latch on the traditional door set broke off. The door latch for you vintage, and mine, is not available and I was advised to buy a set that required cutting the door and riveting on a 12 x 12 plate containing the new set. Not wanting that I had to re-weld the latch after some modifications, for clearance, to the lock body.
The first picture shows the tongue that broke off the latch set. The second shows the latch set and the green tie pointing to the point that failed. the third shows the access holes I had to cut into the interior wall to get access to the bead bolt. Those holes are now covered with 2x4 white plastic electrical covers.
When I welded the tongue back to the slide plate I had to grind some off the cover plate to allow the eld to travel.
