That looks even worse than here. In the US we also have the phenomenon that a series is dropped completely. For example, here at the house we have Zinsco panels for which there are no more breakers. Used ones almost cost collectors prices and aftermarket ones used to be "a Dollar an amp" and now it's more like "two Dollars an amp". -- Regards, Joerg http://www.analogconsultants.com/
