Can I donate Bob Plumb to your collection he's a window cleaner and about 100 years old.
No still don't understand, I must be thick
I think the rubber needs replacing.Seriously though, I find it strange to think that someone was doing the same job way back then in what was, up untill about 10/12 years ago, exactly the same way as all window cleaners.Sod undoing all those screws and then doing them up to replace the rubber.
