Sculptural Danish Table, "Outboard" legs, Dutch leaves, Teak  

johannes andersen maybe???

I searched and searched and couldn't find another like it.
I am not sure I believe that site that it is Johannes Andersen for Uldum. I can't find another by searching anywhere for obvious phrases like "johannes andersen uldum dining table". Or "johannes andersen uldum spisebord". This is not a great sign.
I will keep looking. I found some peculiar leads for Ejvind Johansson and Arne Wahl Iversen, but I think they are dead ends too.

Those radiused leg joints are similar to Andersen's Smile coffee table for CF Christensen Silkeborg. Having said that, the documented Andersen dining table that resembles yours uses 45 degree mitered joints in this area (see photo)

Here are my Ejvind Johansson leads. Similar, but also very different...
(for Ivan Gern Møbelfabrik)

And my Arne Wahl Iversen lead. More similar in one way, and more different in another....

i think the overall shape is closest to other Andersen tables. Definitely the same table as in the FMV ad. Whether it is correctly attributed or not I can't say. I could not find another either. But I love to research so I will keep looking....

My first thought was a Johannes Andersen table as well. Here is another attribution of a similar table with the same leg details. Possibly the earlier tables were built this way. Then, changed to cut costs and production time.

Thinking about it, this joint might have been prone to failure. Which could have led to a change in design. That is if it's even the same table.

I keep coming back to this table, and my first thought is always Johannes Andersen. And then I start digging in to the idea, and it just doesn't work out. And then I start thinking about how he emphasized the legs on his table designs by placing the legs flush to the edge of the table. But this table emphasizes the leg in a different manner: by pulling it out of the plane of the apron. And this just does not seem like Johannes Andersen at all.

Just finished cleaning and re-oiling the table. There are some interesting characteristics. Maybe somebody will recognize something. The pins that hold the top on are freakishly long, and the tips have been pointed by hand.
Also, as you can see the counter veneer is teak, which isn't incredibly surprising, but is one of the features that makes me think it was made by a small shop, not a factory.

At first I thought this was not pertinent to the maker or designer, but maybe it is. The inside of one of the stretchers has been ink stamped "SPONSOR" a few times. Looks like somebody kept at it until they got a clear stamp.

And the top is extremely curly figured teak. The chatoyancy is obviously hard to capture in photos. The maker really wanted this table to be a statement piece.

And a final photo of it all cleaned up.

That table just wants to be kept in the extended position.
I have a similar situation with my Hovmand Olsen dining table that looks great fully extended, but makes access to the other side of the room almost impossible in that state.

Yeah, your table and this one have the same floating effect, but for different reasons, when they are extended. You should consider getting a new room for it! This is what I do when the furniture I want to fit into my space no longer fits.
I am so surprised that such a strong design as this table has been basically impossible to identify.
