djed wroteThe included key is stamped Milner’s Safe Company but the levers seem to be of different designs and I am mot sure it’s original to the lock.
Unfortunately you omitted the very picture we needed to see- showing the levers and inside of your lock.
I’ve seen them fitted on the slightly better offerings from a few old generic British makers so probably not a Milners.
But, the chances of finding a random key that coincidentally fits a 6 or 7 lever safelock with curtain is borderline zero.
It should be obvious when you removed the cover if the lever gatings have been hacked out and the lock butchered to fit the key. It’s sad how many muppets do that in desperation to, in their eyes, make it ‘work’.
There are so many parameters that otherwise need to match perfectly for the key to fit that lock it should be clear whether it was purposely made to fit, or was hacked to pieces afterwards.
Looking at the state of the holes drilled through it, sadly nothing would shock us with that one !
