Extendable dining table in walnut - 1950s

Dining table with extendable leaves on the long sides (up to 107cm). The brass feet are steplessly height-adjustable by means of a patented winder. Tabletop and leaves are walnut-veneered. Traces of handwriting on the surface (no damage to the coating). Apart from that, good vintage condition with only small traces of usage but slight drag marks on the leaves.
