Table No. 312
This folding metal table is an ideal companion to the 221 portable for the small home or apartment. It has a recess which allows the 221 machine to fit flush with the table top, offering ample room for your sewing materials.
A cover which matches the birch top takes the place of the machine, to provide a sturdy, smooth top table for a bridge game or general utility purposes.

The extension has only two legs and attaches to the side of a regular featherweight card table. Both featherweight models 308 and 312 came with extensions. The extensions were models 308 1/2 or 312 1/2.
I've only seen two of these in real life. I spotted them both being used as display tables at a garage sale. The owner used to work for Singer in the 1960's. Unfortunately for me, she knew their value and wasn't about to sell.
*Cutout sizes vary slightly among tables. The overall shape is the same, however.
