I answered an ad for a Singer folding table with 2 legged extension and expect to pick it up later today. It comes with a black crinkle 1942 model 99 in a wooden domed case. In the photo it appears the machine stays in its base and sets into the table, with room to spare. Did Singer make folding tables for specific full sized machines, or is any machine larger than a 221 likely to fit? Can I have a partial wooden cover made so a FW will fit? Does the extension slide into or fold under the table? Have any of you seen a table like this? I am looking forward to having a folding table to use. The table and machine look to be in good condition, the extension has some wear to the top. Thank you.
