This is the lock on my front door. The house was built in the 1960s and I’m pretty sure this is the original door and lock that was installed. There are no identifiers stamped on it, so I have no idea about who the manufacturer may be nor a serial number to use in my [currently] fruitless search for such info.
My goal is to self-service this lock: the bolts don’t spring down with the same force they did even a year ago (it takes multiple hard presses against the plate to get them secured) and the ball&spring in the frame exploded outwards a month ago because the washer that kept them in place worn down too much and the pressure was too much for it.
I could/should probably call a local locksmith but I’d rather try my hand at it first and if I fail, then find someone and be able to supply more information about it than “it’s an old lock, see photos.”
