Set of 4 Baumann Argos model chairs

Set of 4 beech chairs from Baumann, Argos model. Around 1990. The chairs are all stamped Baumann made in France under their crosspiece. They are varnished and honey colored. Some very slight traces of use which are almost not noticed, one chair is very slightly darker than the others (see the photos) the 4 screw covers on all the seats are not original, because some do not have them If you have more, these are made of plastic. The chairs are in very good general condition and stable. I also have a set of 6 identical chairs in my articles on selency.
