Does anyone remember T.G. Berry, the locksmiths in a basement on School Lane.
We used to ask him to make new keys for all the old furniture we rescued from various places, he could make keys for just about any lock.
I used to collect factory clocks - clocking-in machines and the like - and he could make new locks for those as well.
No matter how long you left a lock with him, when you went in to collect it he would say "how long are you in town?" and then "pop back in half an hour".
Then one day we went and the place was all closed up - and we never did get all our locks and clocks back :-(
