Back of mechanism showing the beautifully re-blued gong. If you haven't tried it yet, move your mouse to hover over the mechanism, then, in the menu that apears, click on the "original" size text. It will let you see extreme detail of this mechanism. An interesting point to me is how the oil sinks on some of hte pivots do not align exactly with the pivot holes. Check out the pivot just below the strike arm and the pivot that is the second up from it. Both are offset quite a ways..
