Good catch on both the table and the machine!
I have my Grandma’s folding table that she had for her Singer 404 (I have that too), that looks about like your table. I believe that they’re officially called the “Model 316 Monterey Utility Table”. Mine has stains on it from us kids eating our Potluck meals on it back in the 50s & 60s. Grandma would set it up for us out on the porch because the kitchen was always full of “big people”. I may have caused one or two, so the stains will have to stay.
I look closely at the legs of every folding table that I see in yardsales and markets, looking for another one.....
