danish sofa table - identification

So, a few days ago i let my daughter and my mom do some drawings on a piece of paper, on my sofa table:)
In the end i told them that i should get them another table, i dont want to destroy the surface on my nice sofa table.
"Oh, i'll get you a new one if it gets destroyed" my mom says.

"Oh no, you can hardly get a nice one like this on IKEA" i reply.

"Is it special somehow?" my mom wondered.

Then i realized that it would be nice to know a little more about it. I bought it from an old lady for around $90 (600SEK). It looks like the pics above. Teak i guess, according to the old lady. Likely the 60s ?

Size: 70cm x 40cm - height 50cm (28" x 16" - height 20")

The only markings i can find on it are
* a burnt (?) stamp that probably says "Furniture Makers Danish Control"
* written "NR 242"

So, does anyone have any idea about this? :)
Btw, i live in sweden, close to denmark.
