Walnut swivel desk chair 1920's

Walnut swivel desk chair 1920's. Beautifull complete orginal industrial captain chair that can run and adjust in height. All brass casters are original with 2 still in very good condition and 2 heavy worn but without functional impact. The chair can still be perfectly used for dozens of decades to come. The casters are top quality as they rotate fluently when seated and running the chair which is rare as most casters get stuck by the weight while trying the run the chair. So this chair won't leave scratches or makes on the floor.
