side table ID  

Nice table
It looks like the top is solid teak (end grain is visible). And that is uncommon. Can you confirm it is solid teak? And one thing that might suggest a manufacturer is a close up photo of the tongue and groove joint on the end grain where the staves were glued together.

Hello Leif, attached a picture of the tongue and groove joint, and yes it's solid teak.
Thanks for your help!

looks to me
like a table extension- designed to sit at end of a dining table to enlarge it.

Hi robert, definitely not a dining table extension, height 54 cm!
It's just a very nice side table.

Not much help, but
I have a set of teak nesting tables by Mobelfabriken Toften, which have solid planks connected by a curved "sine wave" tongue-and-groove connection (almost like finger joints).
So, your table is probably not made by Mobelfabriken Toften.

Probably not France and Søn
I've seen two tongue and groove profiles on solid teak Minerva tables by France and Søn (Hvidt & Molgaard), and that isn't either of them. And every photo of their work shows the same profile(s) so it probably isn't France and Søn.
The profile on yours is not one I've seen before, so if some one recognizes it you might have the clue you need to track down a solid ID. And there really aren't an incredible number of makers who used solid teak table tops.

Identification by process of...
Identification by process of elimination? We may be at this one for a while. Okay then, probably not......George Nelson for Arbuck

We might be at this a while
Jesgord: My hope for the OP would be that someone recognizes the table outright, or a least recognizes the profile of that joint.
But you bring up a decent question: how many makers can you think of who made solid teak table tops? I can only think of 5 right now off the top of my head:
France and Son
Soborg
Mikael Laursen
Baker
Johannes Aasbjerg (jesgord: thanks again for confirming this one)
I am sure you can add a few to the list, but are there enough to make the idea of elimination absurd?
Oh, and well done eliminating Nelson for Arbuck. I actually was laughing out loud at that.

This table was designed by Bø...
This table was designed by Børge Rosenbaum for Billige Knald Møbler circa 1964.

Vejle
You can add Vejle to the solid top list.I just sold a round coffee table with 4 wedge shaped store under stools. All teak, and massive too. I was very surprised when I saw the stamp when I acquired the set.

some similarities
in joinery and support structure as well.

Although the table seems
to have a positive id...you're a riot Alice...you might as well add Mobelintarsia to the line-up....I have a nesting table set with all wood tops...each about 3/8th's of an inch thick give or take...

Billige knald
Hey foxxy, I think you should start a Billige Knald Mobler thread on this forum.
I would love, one day, to walk into an antique mall, visit the mid century booth, and see a piece of furniture proudly identified as Billige Knald Mobler by Børge Rosenbaum. With a justiably large price tag. It would make my day.

Børge Rosenbaum for Billige Knald Møbler? Never heard.
