The cylinder arrived in perfect condition and fast. The auszuwechselnde castle had many years (decades) on the clock. The cylinder diameter was perfect, but the old man was a fraction of a millimeter longer and the new did not fit at first. It was only when I extended the snap catches in the two pins with a Drehmel something the new fit now and does its job properly. It has been very gratifying that a metal pin, which is necessary for the reconstruction, was placed.
