Old locks

I hate just buying new stuff when I have old original parts that are usually way better than remade.
I have a Series 2 toolbox door lock. Number 318. I have a NOS key and a recut one ( recut from a different original). The keys will go in the lock, just. The recut is better than the original.
I have just taken the lock into a locksmith. He is going to strip it down and see if he can fix it. But, he isn’t too hopeful as he believes the barrel internals are just worn out and are impossible to get.
Has anyone any words of encouragement for me, other than a complete replacement?
