 He had the answers that you see on the wall there of a mousselail and they came from the bluest in the park expediting right over the doorway. It was made in Mr. Jefferson in the clock in Philadelphia and it does run off weights. Unfortunately you're not able to see they are shaped like cannonballs and are run like these cables. Actually at the end of that cable are eight striking weights that lower each hour when the dog sounds the hour on the break back. And if you are able to see those weights today, the top one in that series would indicate not only the day of the week, but also the approximate hour of the day. For example, midday Wednesday, the top weight between halfway between that Wednesday and Thursday marker and midnight Wednesday would reach that Thursday marker and you'd see that there was not enough wall space for all seven days of the week of space running out early on Friday. So Mr. Jefferson had holes back and above the corners of the floor to allow the weights to pass on through and the Saturday marker is placed on a basic wall of love. So a crank key very similar to the one over there which he used in his day. It forms a narrow three and a half inch wide hole for less noise and storage on the screen. Next today I'm quite sure you don't pick up.
