The extension is a 311 1/2. I have one and it fits on any of the card tables including the FW table. I know because here's my set up. I've been told it's extremely rare and very valuable. The one up for auction is not a FW table.

Candace, how does the extension clip to the main table?

Cathy,
That looks really cool, the extension table connected to the FW table.

I'm not convinced it can hold much weight since it's only clipped onto the table. I would never put another sewing machine on it, for example. It's good for a quilt or piles of fabric, but nothing too heavy. I'm also not a fan of how tight the clips are and they tend to damage the paint finish getting them aligned properly. So, I would set it up and leave it be or be prepared to touch up the paint every so often.
