Following on from my earlier thread I've hopefully got a mate sending me some 1.2mm thick cutoff discs for my angle grinder soon so I can cut through the jammed mortice. After that am I likely to be able to find an identical sized lock to replace this 25 y/o one of unknown origin or is more carpentry likely to be needed? I have no idea if locks have some sort of standardised range of sizes or if every manufacturer does their own thing.
It would be ideal to get one that just slots straight back into the same hole in the door.
