Thanks. Now that would make an impressive item in the house. I do remember the exchange slave clocks in the exchanges when I first worked for BT way back at the beginning of the 70's. There was probably one of the master units somewhere safe in the exchanges but I can't remember seeing them. As for accuracy, it's hardly time-nuts standard at "Clock No, 36 to keep G.M.T. to an accuracy of 8 seconds variation per week" > "Ah, they don't make them like this any more.

And the brass, you can't get brass like that anymore :) > 73 Martin G8BHC > > 2009/3/4 Steve Rooke <[email protected]> > >> Has anyone looked at locking an old mechanical clock to precise time? >> What I'm thinking of is something like an old cuckoo clock.
