This establishes this reed organ as a "chapel back" model, intended for use in churches or other places where the organist needs to face the group. 

#263981 (1893) puts this instrument only a couple of years beyond the great Estey celebration of its 250,000th organ--thus at about the zenith of the reed organ business.  Although the Estey Organ Co. continued until the late 1950's, it was a slow slide downhill.  The rest of the reed organ business was pretty much done by the end of the First World War.  

As screws are removed, they are placed in a muffin tin, and keyed to a reference in my notebook.  This way, when I am reassembling the organ, the screws return to their right places, and assembly proceeds in the right order.  As the screws or other small pieces are put back, they are checked off in the notebook.  There shouldn't be any screws left over! 

The upper parts of the case have been removed, and now the keyboard, too.  The coupler board is seen on the left; then the row of pitmans (or plungers); the front and rear swell shades; the subbass chest on the right, and in the lower right, the tremolo motor and part of the fan.
