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.
