Rare Unknown Nicholas Muller Clock Case Model #4, 1855 - 1860 with Waterbury Movement.

I stumbled upon this clock while perusing my sources, it was listed on eBay, it was a nice clock but it was missing who knows what, besides the clock hands and the wooden back case was in bad shape, so I decided to pass on it. But then I looked again at the detachable top part, and there it was N Muller, NY there is a Number on it also but I couldn't read it from the picture because of the quality on the back of the piece. I looked through Arlyn Rath's book "Nicholas Muller Horologist Extraordinaire" at least four times and it was not listed in it.
Muller often made tops for his clock cases, so they could be used on other clocks according to Rath's book.
There is a museum in Pharr Texas dedicated to his art.
His occupation is listed in the New York city 1870 U S Census as a Bronze Blank Maker.
The movement is in very rough shape but I will try to salvage it.
It is an unknown Muller; it arrived a day early. As ratty as the movement was it still worked with a broken main spring. Its model number is "4".
