who designed and produced this beautiful table?  

@oe. could you post a pic with the table extended as this might help with identification? Thanks

Here is a top iew without the middle part

and here's a look from under..

@oe I eventually found one other table like yours but unfortunately no labels or makers marks !

However it is for sale with some dining chairs with the same legs. Maybe the chairs will jog some other Forum member's memory. I have searched, but no luck so far.

wow! thank you for your effort! nice to see the chairs with it. yes maybe these chairs give a direction. thank you so much! 🌼 

@lexi  Yes, I saw that table and chairs on Pamono as well.

What do you call this type of foot?  It's not a spade foot or ball foot.  I saw a listing for this table by N. Eilersen that calls it a bulb foot.  By the way, this chair with similar feet is attributed to Erik Worts for Eilersen (second picture).  If so, maybe he did the table for them as well.  The feet are similar but not the same as OE's table.

@mark737. I found that Erik Worts chair too. Also , Kaare Klint did a safari chair ,for Rud Rasmussen, with the same feet.

Also this table. Bendt Winge for Aase Dreieri (Norway); again same feet.
