I recently acquired this Singer 128-8.
From this thread over here

apparently Singer bought out Osann which had previously bought out Standard which manufactured a Hexagon (picture at the end of that thread).
Apparently Singer used up parts and made the 128-8. The serial number dates it to 1938 in a lot of 10,000. Makes me wonder if the whole lot was 128-8s.
The cut out on the cabinet would accommodate a 14" base machine, except the hinges are set for a 3/4 size machine, from the left of the cut out. This machine has a spacer on the right which bolts from underneath to the castings in the base. The door is designed to be open and supporting the top, based on the small pad on top of the door and the catch that holds it open. The cabinet is noticeably smaller than one holding a 14" base machine.
The motor may be unique to this machine, based on the mounting rail towards the back of the pillar. The motor itself is also crinkle finish, which I think is kind of cool.
It sews as expected, although I have some work to do on the button style foot control as the machine isn't moving very quickly.
