Dismantled railings for cash?!..

My chirpy window cleaner Darrell, has just raised an interesting point. What happened to all those council railings which have just been, in some cases wrongly, dismantled? Did they go to some dodgy scrap yard specialising in metal for cash? Or are they being recycled in a more responsible manner and the funds put back into council coffers? They'd probably raise a tidy sum, there's alot of metal in those things. Will we ever find out? I said get back to cleaning the windows mate cos you keep missing bits!...
