This Demorest sewing machine is in the The Thomas T. Taber Museum of the Lycoming County Historical Society, Williamsport, PA.
The serial number of this machine is 109155. This machine is probably made in one of the last years of production. The SN is over 27,000 higher than the 1900 machine, and production had slowed down by then. It has the rectangular bed, the drop down cabinet, and the irons do not have the word "Demorest" cast in them. The cabinet has beautiful gold rose decals on the wood. Notice that the shield shaped front inspection plate has a "D" on it instead of the earlier "DSMCo" logo.
