Following Compliments of Sharon Reese:

Red Eye Singer Class 66
Red Eye Singer Class 66

This Singer 66 was made in the 1920's and started out life as a treadle. Later, a Singer dealer added a motor and a numbered tension dial. The decal type is called "red eye" by collectors (There is also some green in the decals). I'm not sure of the exact age of this machine because the serial number was hard to decipher.
