Ikea solid pine wood table and chairs from the 80s?

Hello I own a great round / oval (extendable) solid beech table and six chairs with blue and white upholstery. Since I bought them second-hand when I moved into my first own apartment, I didn’t even know at first that the furniture was from Ikea. Now they have accompanied me wonderfully for the last ten years and are still in very good condition. But now I would like to pass them on and some time ago I found pictures of exactly this table on the cover of an old Ikea catalog. Unfortunately, I have not been able to find out the name so far. Maybe someone here knows the names?

Hello, the chair should be a KRISTINA, the table possibly GILLE. GILLE is made of pine, has a diameter of 120 cm, is 200 cm long with 2 extension leaves, and the tabletop is 38 mm thick.

So the total length of the table is 195 cm, diameter as a circle 115 cm, the thickness 27 or 28 mm. Does that still fit then?

No, the plate will not have shrunk to 1 cm thin.

In the 90s, there was also GILLE, but it has become smaller at 117 and 197 cm. The board thickness is no longer specified, but it looks thinner than before.

Unfortunately, I can't find any pictures online when I search for Gille. The group could also be from the 90s; the 80s was just an estimate from me :) Unfortunately, I also can't find any pictures for comparison under the chair name.
